X= -3
-3+-3=-6 +1= -5 and there are 5 red squares
X+6y+22 combine like terms
Answer:
16 degrees
Step-by-step explanation:
<u><em>The question is</em></u>
Find the measure of angle R
we know that
An exterior angle of a triangle is equal to the sum of the opposite interior angles
so
In this problem

we have

substitute


Because it is a quadrilateral, all 4 angles have to add up to 360 degrees.
Add the 3 known angle measures.
80+95+38=213
Then subtract from 360.
360-213=147
X=147 degrees
