The third side of a triangle can be found using the Pythagorean Theorem.
The Pythagorean Theorem states that for a triangle with sides of length a, b, and c (with c being the length of the unknown side) a^2 + b^2 = c^2.
To find the third side of a triangle that is not right, first calculate the lengths of the two known sides. Let's say the lengths of the two known sides are a = 5 and b = 12.
Next, plug the values into the Pythagorean Theorem and solve for c.
[tex]a^2 + b^2 = c^2[/tex]
[tex](5)^2 + (12)^2 = c^2 \\25 + 144 = c^2[/tex]
[tex]169 = c^2[/tex]
Finally, take the square root of both sides to solve for c.
sqrt(169) = c
13 = c
Therefore, the length of the third side is 13.

Answer:
25%
Step-by-step explanation:
Of the 12 girls and 16 boys in Mr. Johnson's class, 3 girls and 4 boys wear glasses. You want to know the percentage of students in the class who wear glasses.
PercentageThe percentage is the fraction multiplied by 100%. The fraction is the ratio of glasses-wearers to total students.
percentage = (girls w/ glasses + boys w/ glasses)/(girls + boys)×100%
percentage = (3 +4)/(12+16) × 100% = 7/28 × 100% = 25%

How do you solve for asymptotes?
There are three types of asymptotes solved in the following way:
1. Horizontal asymptotes is y = k for x→∞ and x→ -∞ , when degree of denominator > degree of numerator.
2. Vertical asymptote is x = k for y→∞ and y→ -∞ , when degree of denominator < degree of numerator.
3. Slant asymptotes is y = mx + c.
Asymptote is the representation of the line which approaches to the given curve but never touch or meet with the curve.Three types of asymptotes : Horizontal asymptote, vertical asymptote, and the slant asymptote.1. Horizontal asymptotes is y = k for x→∞ and x→ -∞ , when degree of denominator > degree of numerator. 2. Vertical asymptote is x = k for y→∞ and y→ -∞ , when degree of denominator < degree of numerator. 3. Slant asymptotes is y = mx + c.Horizontal asymptote rarely cross the given curve but vertical asymptote never.Slant asymptote represents the slope of the function.Therefore, the three types of asymptotes solved in the following way:
1. Horizontal asymptotes is y = k for x→∞ and x→ -∞ , when degree of denominator > degree of numerator.
2. Vertical asymptote is x = k for y→∞ and y→ -∞ , when degree of denominator < degree of numerator.

The two smaller angles of a right triangle have equal measures. find the measure of all three angles.
Answer:
Step-by-step explanation: Because all three angles of the triangle must equal to 180 degrees, the two smaller angles of the right triangle must be 45 degrees. This is because a right angle always is 90 degrees and because you know that the other two angles are the same, and it must all equal to 180, the angles must be 45 degrees, 45 degrees, and 90 degrees.
Angle 1: (right angle) 90 degrees
Angle 2: 45 degrees

How do you find the equation of a vector given the point and direction?
To find the equation of a vector given a point and direction, you need to find the components of the vector and plug them into the equation: v = (x, y, z).
The equation of a vector is typically written like this:
v = (x, y, z)
To find the equation of a vector given a point and direction, you need to find the components of the vector and plug them into the equation. For example, let's say you are given the point (1,2,3) and the direction of the vector is (2,3,4). The components of the vector, v, would be x = 2, y = 3, and z = 4, so the equation for that vector would be:

An equilateral triangle has sides 12cm in length. Calculate the
perpendicular height of the triangle. (to the nearest mm)
Help please
Answer:
10 mm
Step-by-step explanation:
Draw an equilateral triangle. Label each side 12 mm.
Draw one altitude from one vertex perpendicular to the opposite side. Label the length of the altitude h.
The altitude divided the opposite side into two congruent segments, each one measuring 6 mm.
Now use the Pythagorean Theorem.
a² + b² = c²
(6 mm)² + h² = (12 mm)²
36 mm² + h² = 144 mm²
h² = 144 mm² - 36 mm²
h² = 108 mm²
h = 6√3 mm
h ≈ 10 mm
Answer: 3.5 cm or 35 mm
Step-by-step explanation:
12/3 =4 for each side of triangle
cutting the triangle in half, bottom side(a) 4 becomes 2
2^2 + b^2 = 4^2
4 + b^2 = 16
subtract 4 from both sides
b^2 = 12
b = 3.464 cm or 3.5 cm
convert 3.5 cm to 35 mm

The given set of ordered pairs does not satisfy a linear function.
What is a linear function?A linear function is one that, when plotted, forms a straight line. Therefore, non-linear functions are all non-linear functions. We can discern if a function is linear or non-linear from its input/output table or equation, but graphing may be the quickest way to do it.
Given:
The given set of ordered pairs is:
{(3, 2), (4, 3), (5, 4), (6, 5)}
To find:
Whether the given set of ordered pairs satisfies a linear function or not.
Explanation:
The slope of a linear function is:
m = (y₂ - y₁)/ (x₂ -x₁)
The slope of the linear function passes through the points and is:
m₁ = (3-1)/(3-1)
m₁ = 2/2
m₁ = 1
The slope of the linear function passes through the points and is:
m₂ = (9-3)/(5-3)
m₂ = 6/2
m₂ = 3
Therefore m₁ ≠ m₂ therefore the given set of ordered pairs does not satisfy a linear function.

4x + 8y = 242x + y = 193x + y = 154x + 2y = 12x + y = 11x + 2y = 10Let's eliminate the variable y by adding equations 1 and 2:

6x + 9y = 43
Now we can eliminate the variable x by subtracting equation 3 from the above equation:
6x + 9y = 43
3x + y = 15
.
.
.
3x + 8y = 28
We now have an equation with one variable: 3x + 8y = 28. We can solve for x by dividing both sides by 3:
x = (28 - 8y) / 3
Now we can substitute this expression for x into one of the original equations and solve for y. Let's use equation 4:
4x + 2y = 12
Substituting x = (28 - 8y) / 3:
4((28 - 8y) / 3) + 2y = 12
If we simplify:
28 - 8y + 2y = 128y = 16y = 2Finally, we can use this value of y to find x by plugging it into the expression we found earlier:
x = (28 - 8(2)) / 3
x = (28 - 16) / 3

[tex] \sf \: x=\frac{16}{2} \\ [/tex]
Divide 16 by 2.
[tex] \boxed{ \boxed{ \bf \: x=8 }}[/tex]
Now solve the equation [tex]\sf\:x=\frac{2±14}{2} [/tex] when ± is minus. Subtract 14 from 2.
[tex] \sf \: x=\frac{-12}{2} \\ [/tex]
Divide -12 by 2.
[tex] \boxed{\boxed{ \bf \: x=-6 }}[/tex]
The equation is now solved.
[tex] \underline{ \bf \: x=8 }\\ \underline{ \bf \: x=-6 }[/tex]
what is the slope intercept form of this equation: -12x + 3y = 3*
Answer:
y=4x+1
