Question

i got three questions wrong on my homework i need help

Answer 1

How many sides are there?

remember the formula for the sum of interior angles is
(sides - 2) * 180

Answer 2

and so all those numbers in the image (including x and 2x) will have to add up to whatever number you calculate

and then you just solve for 'x'

Answer 3

x + 143 + 2x + 152 + 116 + 125 + 140 + 139 = whatever number

so how many sides are there?
count the sides
subtract 2 from it
and then multiply it by 180

and so x + 143 + 2x + 152 + 116 + 125 + 140 + 139
is going to be equal to that number you just got

Answer 4

and then you solve for 'x'
