Answer:
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relevant trig relations:
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
__
In this triangle this means ...
sin(50°) = b/14 ⇒ b = 14·sin(50°) ≈ 10.7
cos(50°) = a/14 ⇒ a = 14·cos(50°) ≈ 9.0
Of course, the other acute angle, A, is the complement of the given one:
A = 90° -50° = 40°
So you have ...
