Step-by-step explanation:

Always remember the formula:

tan x = (sin x)/(cos x)

[tex]tan \: x = \frac{sin \: x}{cos \: x} \\ = \frac{ \frac{24}{25} }{ \frac{7}{25} } \\ = \frac{24}{7} [/tex]

Answer:

30°

Explanation:

∠LMP + ∠PMN = 180°

[∠LMO + ∠OMP] + [∠PMR + ∠RMN] = 180°

FIND x

(x - 10) + (x + 30) + x + 40 = 180

3x - 10 + 30 + 40 = 180

3x + 60 = 180

3x = 120

x =40

FIND ∠LMO

∠LMO = x - 10

∠LMO = (40) - 10

∠LMO = 30°

Hope this helps and God bless!

Answer:

∠LMO = 30°

Step-by-step explanation:

Angles on a straight line add up to 180°

⇒ (x - 10)° + (x + 30)° + 40° + x° = 180°

⇒ x° + x° + x° - 10° + 30° + 40° = 180°

⇒ 3x° + 60° = 180°

⇒ 3x° = 120°

⇒ x = 40

Substitute found value of x into the expression for ∠LMO:

⇒ ∠LMO = (40 - 10)°

⇒ ∠LMO = 30°

[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]

The sum of the probabilities of all outcomes must equal 1

Solution

We are told that the probability that the counter is not black is 3/4.  

As the sum of the probabilities of all outcomes must equal 1, we can work out the probability that the counter is black by subtracting 3/4 from 1:

[tex]\sf P(counter\:not\:black)=\dfrac34[/tex]

[tex]\implies \sf P(counter\:black)=1-\dfrac34=\dfrac14[/tex]

We are told that the probability that the counter is not white is 2/3.  

As the sum of the probabilities of all outcomes must equal 1, we can work out the probability that the counter is white by subtracting 2/3 from 1:

[tex]\sf P(counter\:not\:white)=\dfrac23[/tex]

[tex]\implies \sf P(counter\:white)=1-\dfrac23=\dfrac13[/tex]

We are told that there are black, white and grey counters in the bag.  We also know that the sum of the probabilities of all outcomes must equal 1.  Therefore, we can work out the probability the counter is grey by subtracting the probability the counter is black and the probability the counter is white from 1:

[tex]\begin{aligned}\sf P(counter\:grey) & = \sf1-P(counter\:black)-P(counter\:white)\\\\ & =\sf 1-\dfrac14-\dfrac13\\\\ & = \sf \dfrac{12}{12}-\dfrac{3}{12}-\dfrac{4}{12}\\\\ & = \sf \dfrac{12-3-4}{12}\\\\ & = \sf \dfrac{5}{12}\end{aligned}[/tex]

Answer:

30 inches

Step-by-step explanation:

In equilateral triangle all sides are equal. One side of the triangle EB is also the  side of a square.

So, all the sides of the square is 6 inches

Perimeter = sum of all sides

                  = AB  + BC + CD + DE + EA

                  = 6 + 6 + 6 + 6 + 6

                  = 5*6

                   = 30 inches

Answer:

Here,

length of the square BCDE(l)= 6 inches

Also,

length of the equilateral triangle ABE(l)=6 inches

Lastly, Perimeter of figure ABCDE= 5*6

=30 inches

or,Perimeter of the figure ABCDE also=

AB+BC+CD+DE+EA

=6+6+6+6+6

=30inches

Step-by-step explanation:

We know,

length DC of the square BCDE(l)=6inches

So,

DC=BC=BE=DE (All sides of a square are equal)

Again,

length BE of the equilateral triangle ABE=6inches

So,

BE=AB=AE (All sides of a equilateral triangle are equal)

Therefore, Perimeter of figure ABCDE=

AB+BC+CD+DE+EA or, 5*6

(perimeter means to sum all the outer sides a given polygon, in this case it's a Pentagon)

Answer:

The answer to 6^4 is 1296

Step-by-step explanation:

2x2x2x2 = 16 (you have to multiply the 2 four times because you have a little four on top of the two)

3x3x3x3 = 81 (you have to multiply the 3 four times because you have a little four on top of the three)

16x81 = 1296 (6^4 = 6x6x6x6 = 1296)

Answer:

(a) Reduction

(b) scale factor = 1/2

Step-by-step explanation:

(a)  A reduction is a dilation that creates a smaller image.  

As A'B'C'D' is smaller than ABCD, image A'B'C'D' is a reduction of image ABCD.

(b)  To find the scale factor:

center of dilation = (0, 0)

(0, 0) to point C = 4 units

(0, 0) to point C' = 2 units

⇒ scale factor = 2/4 = 1/2

A circle is a curve sketched out by a point moving in a plane. The measure of x is 60°.

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

Given that the measure of the arc AC is 120°. Now, as we know, the diameter divides the circle into two equal chords of 180° each. Therefore, the measure of x can be written as,

[tex]x = {\rm arcAB-arc AC}\\\\x = 180^o-120^o\\\\x = 60^o[/tex]

Hence, the measure of x is 60°.
