Question

Angle M and angle R form a supplementary angle.

The measure of Angle R is 40+2x.
The measure of angle M is 13x.
What is the value of x

Answer 1

`x = 9.33(appx)`

Explanation:

If two angles form an supplementary angle, their sum will be 180°.

In the question , angleM & angleR form a supplementary angle.

`= > 13x + 40 + 2x = 180`

`= > 15x + 40 = 180`

`= > 15x = 180 - 40 = 140`

`= > x = (140)/(15) = 9.33(appx)`
