Answer:
A) sum = (180)(20) = 3600°
Step-by-step explanation:
The formula for the sum of interior angles for any polygon is (n-2) x 180° with n being the number of sides the polygon has.
We can just plug in 22 into the equation to get our answer:
(22-2) x 180°
= (20) x 180°
= 3600
3(x+5)+2x
First, distribute 3 to all terms within the parenthesis
3(x) = 3x
3(5) = 15
3x + 15 + 2x
Combine like terms
(3x + 2x) + 15
5x + 15
(B) is your answer
