Question

Find the value of x

Answer 1

Answer: x = 135

Steps:
(x - 5) + 50 = 180
x - 5 = 180 -50
x - 5 = 130
x = 130 + 5
x = 135

Check:
(x - 5) + 50 = 180
(135 - 5) + 50 = 180
130 + 50 = 180
180 = 180 ✅

Answer 2

x=135

Explanation:

The two angles are supplementary, meaning they both add up to 180°.

So to find the value of one angle, simply subtract 50 from 180.

180-50=130

So now we know that 130 is equal to the expression.

x-5=130

Add 5 to both sides.

x=135
