Question

Given the diagram of the right angle below, find the value for x. ​

Answer 1

x = 23

Explanation:

the right angle is formed by the angles (3x - 25)° and (2x)° , that is

3x - 25 + 2x = 90 ( simplify left side )

5x - 25 = 90 ( add 25 to both sides )

5x = 115 ( divide both sides by 5 )

x = 23
