Find the value of x.

66

Step-by-step explanation:

subtract each external angle by 180 to find the interior angle.

Since you know that all of the interior angles add up to 540 because 180(n-2)

with n is how many sides in the polygon

so 180(5-2)=540

now take each value and subtract it by 180

180-(45)=135

180-(40)=140

180-(x)=180-x

180-(77)=103

180-(2x)=180-2x

135+140+180-x+103+180-2x=540

738-3x=540

x=66

hope that helps :)

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
