Answer:
see the explanation
Step-by-step explanation:
we know that
The sum of the interior angles in any polygon is given by the formula

where
n is the number of sides of the polygon
step 1
Find the sum of the interior angles in the given polygon
we have

substitute

step 2
Find the value of x
we know that

solve for x


step 3
Find the measure of each interior angle
substitute the value of x
Angle A

Angle B

Angle C

Angle D

Angle E

Ok since the athlete an equal distance of 2 days a week and he runs a total of 11 miles in 5 days you will need to think back so before he had 11 miles done next weak he had a total of 19 miles so you will start at 11 then count up to 19.
Use a number line to show how many days it took for the athlete to get 19 miles.
Then once you do the number line count the lumps and that’s how many days it took for the athlete to get 19 miles.
Hope this helped.
