Answer: 78°
Similar triangles are different from congruent triangles. Congruent triangles have equal angles and sides, while similar triangles have equal angles and proportional side lengths. In this case, because the triangles are similar, the angles should be equal. The sum of the angles of triangles are always 180°. Because triangle ABC has angle measures of 28° and 74°, the equation should appear as 28+74+x=180. Add the like terms to get 102. Subtract 102 on both sides to get x=78. Although we only solved for Triangle ABC, again, similar triangles have the same corresponding angle measures, so it applies to Triangle DEF, as well.

7x320=2240
Suppose the following triangle is isosceles. Find the value of x.
Answer:
x = 62
Step-by-step explanation:
Because of the given congruent sides, the base angles both measure x.
x + x + 56 = 180
2x = 124
x = 62
if the triangle is an isosceles triangle then x is equal to the other angle that is unknown. So
180-56=124. Since there are still 2 angles left you divide 124/2=62
x=62

Find the inverse of the function f(x) = 2÷3x -6
Answer:
f⁻¹(x) = 3/2x +9
Step-by-step explanation:
You want the inverse of the function f(x) = 2/3x -6.
Inverse functionThe inverse function can be found by solving for y:
x = f(y)
Here, that is ...
x = 2/3y -6
x +6 = 2/3y . . . . . . . . . . . . . . add 6
y = 3/2(x +6) = 3/2x +9 . . . . multiply by 3/2
The inverse function is f⁻¹(x) = 3/2x +9.
__
Additional comment
Sometimes the division symbol ÷ is used to mean "divided by everything after this symbol." If that is the intended meaning, the function should be written as f(x) = 2/(3x -6) or f(x) = 2÷(3x -6).
We have interpreted the symbol according to the order of operations, which tells us that 2÷3x-6 means ((2÷3)·x)-6.

4) It was recommended that the trees be planted 10 feet apart. The school chose to plant the first tree 15 feet away from the property line fence and then to space the trees 10 feet apart accordingly. Write a linear equation with y representing the total distance (in ft.) away from the property line fence and x representing the number of trees used.
a) Write another linear equation for this situation but use a different form.
b) Graph the situation described in question #4.
The linear function that model this problem is y = 10x + 15 and in standard form is 10x - y = -15
What is a Linear EquationA linear equation is an algebraic equation in which each term is either a constant or a product of a constant and a single variable. It is of the form ax + b = 0, where a and b are constants and x is a variable.Sometimes, a linear function can also be said to be a linear equation which is an equation that can be written in the form Ax + By = C, where A, B, and C are constants and x and y are variables. Linear equations are used to describe relationships between two variables, and they can be used to solve a wide range of problems.
In this problem, we can write an equation in slope-intercept form.
This can be modelled in y = mx + c
To model the problem,
y = 10x + 15
a) To rewrite the problem in another form of linear equation, we can write this in the standard form.

We have given that,
A mother tracks the duration of her baby's three daily naps for a few weeks. The mean time, in minutes, and the standard deviation, SD, for each nap are recorded in the table below.

Write a division problem that has a quotient of 9/10 . At least one of the numbers you give must be a proper fraction. The other can be a proper fraction, whole number, or improper fraction. Neither the dividend nor the divisor can be 9/10 .
By dividing we can get proper fraction is 9/10.We can find answer by dividing two fractions.
What is proper fraction with example?A proper fraction is a fraction which has its numerator value less than the denominator. For example, ⅔, 6/7, 8/9, etc. are proper fractions.. We simplify fractions because it is always to work or calculate when the fractions are in the simplest form.
How do you divide fractions?To divide a fraction with a whole number we multiply the given whole number with the denominator of the fraction. Here, 8/5 ÷ 5 = 8/5 × 1/5 = 8/25. Therefore, 8/5 ÷ 5 = 8/25. Because multiplication is easier than division and because division by itself does not always produce whole numbers.

What is recursion ?
It is a process in which it calls itself to solve the given problem is called as recursion.
The recursive formula to find the nth term of a geometric sequence is:
an = an-1 * r for n ≥ 2
In Brett's case,
if n=2
a2 = a1 * r
given a2 = 10 a1 =5
10 = 5 *d
d=2
a4 = a3 * d = 20*2 = 40
a5 = a4*d = 40*2 = 80
a6 = a5*d = 80*2 = 160
a7 = a6 * d = 160*2 = 320
In Yolanda case,
The recursive formula to find the nth term of an arithmetic sequence is:
an = an-1 + d for n ≥ 2
if n=2
a2 = a1 + d
60 = 25 + d
d = 35
a4 = a3+d = 95 + 35 = 130
a5 = a4+d = 130 + 35 = 165
a6 = a5+d = 165 + 35 = 200
a7 = a6 +d = 200 + 35 = 235
Hence the pattern in Brett's case could be 5,10,15,20,25,30,35 and in Yolando's case could be 25,60,95,130,165,200,235 .
