Determine the value of x in each figure.
PLEASE HELP

x=3

Step-by-step explanation:

Hello There!

The shown angles have a sum of 90 degrees

This is noticeable because there is a square at the vertex which indicates that its a right angle

A right angle has a measure of 90 degrees

That being said we can create an equation to solve for x

90 = 66 + 8x having made an equation we now solve for x

step 1 subtract 66 from each side

90 - 66 = 24

66 - 66 cancels out

now we have

24 = 8x

step 2 divide each side by 8

8x/8=x

24/8=3

we're left with x = 3

x=3

Step-by-step explanation:

8x+66=90 complement

8x=90-66

x=24/8=3

is this a multiple choice question?

if so it's a and c
