Answer:
x = 84
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, thus
sum = 180° × 3 = 540°
Sum the interior angles and equate to 540 for x
131 + 108 + 107 + 110 + x = 540, that is
456 + x = 540 ( subtract 456 from both sides )
x = 84
Answer y=40
Step-by-step explanation:
its split in half so if one side is 40 that means the other side is to
Given:

.
Where are the equations and then I am happy to help.

=0 is the answer
Factor it (x+3)(x-1)
Set each to 0 x+3=0 and x-1=0
Solve each for x x=-3 and x=1
Ta da :)
Hope that helps
