Question

2) sin X Z 45 36 X 27 Y A) B) no+ D)

Answer 1

$B)\frac{4}{5}$

Explanation

For the angle α, the sine function gives the ratio of the length of the opposite side to the length of the hypotenuse.

$\sin \alpha=\frac{\text{opposite side}}{\text{hypotenuse}}=\frac{y}{z}$

then, Let

$\begin{gathered} \text{opposite side= 36} \\ \text{hypotenuse =45} \\ \text{angle}=\angle x \end{gathered}$

Now, replace

$\begin{gathered} \sin \alpha=\frac{\text{opposite side}}{\text{hypotenuse}} \\ \sin \angle x=\frac{36}{45}=\frac{12}{15}=\frac{4}{5} \\ \sin \angle x=\frac{4}{5} \end{gathered}$

so, the answer is

$B)\frac{4}{5}$
