Answer 7

You can find sides of triangle using Law of cosines
\[a^2 = 8^2 + 8^2 - 2(8)(8) \cos \theta\]

you can find heights of each smaller triangle using sine
\[h = 8 \sin \theta\]

Answer 8

Thank you sir, I did that a few minutes ago since it took too long for someone to respond xD, i found that the area of the triangle was 79.80 and the area of the circle was 201.06, subtracting the former with the latter gives me 121.26 units squared.

Answer 9

lol, messed up with former and latter, i meant latter with former xD
