How do I find the measure of the interior angle?

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

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
