Question

Find the value of x. what is the relationship of these 2 angles? set up and solve an equation

Answer 1

x = 20°

Explanation:

`2x + 5 + x + 25 = 90 \\ 3x + 30 = 90 \\ 3x = 90 - 30 \\ 3x = 60 \\ x = (60)/(3) \\ x = 20 \\`

Answer 2

As it is right angled, thus it will be equal to 90.

= 2x + 5 + x + 25 = 90

= 3x + 30 = 90

= 3x = 60

= x = 60/3

= x = 20
