1) Find H using phythagoras
2) Find F° then inverse to find F°
3) Find sin G° and consequently G°
4) Check that 90° F° G° =180°
5) Finally check that cosF° when inversed gives you the same answer
H=4^2 2^2=H
16 4=20
H=sqr20
= 4.47
2) Tan =F 2/4=0.5 tan-1
=26.56
I'm kind of stuck on how to work the rest
Hypontenuse = H
