Answer:
∠ A ≈ 52°
Explanation:
using the law of sines in Δ ABC
=
=

where a, b and c are the sides opposite ∠ A, ∠ B and ∠ C
here a = 25 and b = 28
using the first 2 ratios from the law of sines to find ∠ A
=
( cross- multiply )
28 × sinA = 25 × sin62° ( divide both sides by 28 )
sinA =
, then
∠ A =
(
) ≈ 52° ( to the nearest degree )
