Answer:
a) θ = 14°
b) θ = 62°, A = 28°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relation ...
Tan = Opposite/Adjacent
This is the useful relation in each case.
__
a) tan(θ) = 43/172
θ = arctan(43/172) ≈ 14°
__
b) tan(θ) = 32/17
θ = arctan(32/17) ≈ 62°
A = complement of θ = 90° -62° = 28°
