Question

The angles shown below are supplementary:

A pair of supplementary angles is shown. One angle measures 10x and the other angle measures 60 degrees.

What is the value of x?

6°
9°
12°
18°

Answer 1

I wanted someone to check my answer which was 6

Answer 2

add the angles and equate it to 180

10x + 60 = 180 ....
10x + 60 = 180
- 60 -60
--------------
10x + 0 = 120

so, now we can focus on:


10x = 120
the 10x = 120, when x=12
So C
