Question

Find all the missing parts to the triangle below.

Answer 1

I am going to call the triangle FGH with F the bottom left angle and working in a clockwise direction.
h = 22 H = 87 f = 12
We need to find F, G and g.
F first.
Sin F/ 12 = Sin 87/22
Sin F = Sin 87 * 12/22
= 0.5447
F = 33.0 degrees
G = 180 - (87 + 33) = 60 degrees
g/sin 60 = 22/sin 87
g = 22 sin60 / sin 87
= 19.1
