Answer:
132°
Step-by-step explanation:
We will using exterior angle property which states that sum of two interior angles equals to the exterior angle.
60° + 72° = x
132° = x
Hence, exterior angle 'x' measures 132°.
Answer:
x = -9
Step-by-step explanation:
-4x = -1/2(10x + 18)
Distribute
-4x= - 5x -9
Add 5x to each side
-4x+5x = -5x+5x -9
x = -9
Factoring the roots, the values of A and B are given as follows:
<h3>What are the values of A and B?</h3>
The expression is:

We have that:

Hence:

Hence, comparing the last two equalities:
