Question

Please help answer this and explain it clearly thanks!!

Answer 1

Answer:

∠CAB = 48.81 degree.

Step-by-step explanation:

Let us consider, ∠CAB = $\alpha$

From figure,

        $tan \alpha = \frac{BC}{CA} \\tan\alpha = \frac{8}{7} \\ \alpha = tan^{-1} (\frac{8}{7} )\\\alpha = 48.81 degree$

Answer 2

Answer:

∠ A ≈ 48.81°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan A = $\frac{opposite}{adjacent}$ = $\frac{BC}{AC}$ = $\frac{8}{7}$ , thus

A = $tan^{-1}$ ( $\frac{8}{7}$ ) ≈ 48.81° ( to the nearest hundredth )
