x = 56.31%

Step-by-step explanation:

to find x, use $tan^{-1}$

$tan^{-1}$ x = $\frac{opposite}{adjacent}$

$tan^{-1}$ x = $\frac{15}{10}$

$tan^{-1}$ x = 1.5

x = 56.3099

56.3099 = 56.31

If 8x+6=4x+38
8x-4x=38-6
4x=32
x=32/4=8

Angle of A is equal to angle of B (mirrored)

Then angle of B is 4x+38 = 4*8+38 = 32+38=70

The number of ways to choose the colors is 36

<h3>How to determine the number of ways?</h3>

The given parameters are:

Colors = 9

Colors to choose = 7

Since order does not matter, then it is combination

This is calculated using:

$^nC_r = \frac{n!}{(n - r)!r!}$

This gives

$^nC_r = \frac{9!}{7!2!}$

Evaluate

$^nC_r = 36$

Hence, the number of ways is 36
