My answer is in the photo above
Looking at the problem, what we must do to complete this question is to completely factor the expression that was provided. The expression that was provided is
.
The first step that we must do is to take a look at the expression and see what the two pieces of the expression have in common. We can see that both
and
have the number 5 and the variable c associated with them so we can factor out those two.
<u>Factor out 5c</u>
Now we have completely factored out the expression that was provided in the problem statement and we came to final answer of
.
Answer:
127°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180°(n - 2) ← n is the number of sides
here n = 5 ( Pentagon), hence
sum = 180° × 3 = 540°
To find the fifth angle subtract the sum of the 4 given angles from 540
angle = 540° - (156 + 72 + 98 + 87) = 540° - 413° = 127°
