Answer:

∠ A ≈ 77.8°

Step-by-step explanation:

Using the Sine rule in Δ ABC

$\frac{BC}{sinA}$ = $\frac{AB}{sinC}$

$\frac{37}{sinA}$ = $\frac{29}{sin50}$ ( cross- multiply )

29 × sinA = 37 × sin50° ( divide both sides by 29 )

sinA = $\frac{37sin50}{29}$ , then

A = $sin^{-1}$ ( $\frac{37sin50}{29}$ ) ≈ 77.8° ( to 1 dec. place )
