7 an obtuse angle and a acute angle are shown, 54° (for number 1) and 126° (for number 2) are missing.
8. an obtuse and a acute angle are shown, 45° (for 1) and 135° (for 2) are missing.
Answer - to solve for the equivalent equation of r you would need to use the formula r=c/pi2.
4x + 2x + 2
= 6x + 2
So the answer is B
