Question

Find the value of x.
and please show how you got to the answer

Answer 1

Because a triangle is 180 degrees, and you already have a right angle that leaves 90 degrees for the rest of the angles.

So, (2x) + (x+15) = 90

Combine like terms.

3x + 15 = 90

Subtract 15 from 90.

3x = 75

Divide.

75/3, so x = 25.
