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°
