Given the triangle DEF.
Angle E = 71.2˚
e = 29.5 cm
f = 30.3 cm
We are to solve for each triangle.
Using laws of sine:
a = b = c
sinA SinB SinC
In this case we will have:
e = f
SinE SinF
29.5 = 30.3
sin 71.2˚ sinF
cross multiply
sinF(29.5) = sin 71.2˚(30.3)
sinF = sin 71.2˚(30.3)
sin 29.5
sinF = 0.9466 * 30.3
0.4924
sinF = 58.2524
