Answer:
alright
Step-by-step explanation:
For a 30-60-90 triangle
if the shorter leg (oposite 30 degrees) is x then the other leg is x√3 and the hyptonuse is 2x
so
hyptonuse=8
8=2x
4=x
longer leg is 4√3, yep
so shorter leg or height will be 4 units
First of all, it is 2r
and it would be divide by 3.14 (pi) and then you should have the diameter. Then divide by 2 to find radius.

Matt's steps will be more complicated since Annie is using a program to do the constructions hers would probably be precise and easy.
17 = p - 3 - 3p
17 = -2p - 3
17 + 3 = -2p
20 = -2p
-20/2 = p
-10 = p <==
