Question

Pls tell me some answers for this

Answer 1

Answer:

∠B ≈ 56.25°

Step-by-step explanation:

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

cosB = $\frac{adjacent}{hypotenuse}$ = $\frac{BC}{AB}$ = $\frac{5}{9}$, thus

B = $cos^{-1}$($\frac{5}{9}$ ) ≈ 56.25°

Answer 2

Answer:

∠B = 56.25

Step-by-step explanation:

We would use cosine function here.

cos Θ = $\frac{adjacent}{hypotenuse}$

cos Θ = $\frac{5}{9}$

cos⁻¹ ($\frac{5}{9}$) = 56.25
