Question

What is the measure of Angle F?

Answer 1

is it 146

Answer 2

This should help you out, since you know that a triangle always has only 180 degrees in it. You can use this strategy on all your tests to break up polygons.

Answer 3

720 degrees total right?

Answer 4

A circle has 360 degrees, I don't know if 720 is right, but it sounds good I think.

Answer 5

6*180 =1080-360

Answer 6

Yep, you got it. Should just become a simple algebra equation now to solve. =)

Answer 7

so mat is right?

Answer 8

Haven't checked, but I guess so if you got the same answer.

Answer 9

(10x-4)+(10x-4)+(5x+8)+(5x+8)=458 (<- 720-other angles) x=15. 10(15)-4=146
you're welcome ;D
