Answer:

∠B = 56.25

Explanation:

We would use cosine function here.

cos Θ =
(adjacent)/(hypotenuse)

cos Θ =
(5)/(9)

cos⁻¹ (
(5)/(9)) = 56.25

Answer:

∠B ≈ 56.25°

Explanation:

Since the triangle is right use the cosine ratio to solve for B

cosB =
(adjacent)/(hypotenuse) =
(BC)/(AB) =
(5)/(9), thus

B =
cos^(-1)(
(5)/(9) ) ≈ 56.25°
