Question

What is the value of x?

Answer 1

x = 41

Explanation:

Since they are vertical angles, 90 = 2x + 8.

Then isolate the variable by subtracting 8 from both sides.

So 2x = 82.

Then divide each side by 2 to get x = 41.

Answer 2

The little rectangle in the top right means the angle is a right angle which equals 90 degrees.

This also means all the other angles are also 90 degrees.

Solve for x:

2x+8 = 90

Subtract 8 from both sides:

2x = 82

Divide both sides by 2:

x = 82/2

x = 41
