I know its a vertical angle, and I know I am supposed to subtract 180 but I can't figure what to subtract from 180. Thanks for anyone who can provide me help.

Answer 1

that square marker in the angle means the angle is 90 degrees

Answer 2

so 2x + 38 = 90

Answer 3

I'll let you solve for x

Answer 4

You don't have to subtract 180 from anything. It is given that the angle = 2x + 38. And since it is a right angle, the angle must be 90. To find the value of x you make the equation: 2x + 38 = 90
You have to get the variable(x) by itself. Subtract 38 from each side.
2x = 52
Divide 2 from each side.
x = 26

The answer is A.
