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

Answer:

$x = 9.33(appx)$

Step-by-step explanation:

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

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

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

$= > 15x + 40 = 180$

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

$= > x = \frac{140}{15} = 9.33(appx)$
