Question

Which of the following is a correct equation based on the triangle shown?

Answer 1

The correct answer is 0.766 = x/12

Explanation:

Answer 2

Correct choice is B

Explanation:

Unknown leg x in right triangle is opposite to the angle of the measure of 50°. Use the definition of the sine of the angle:

`\sin \alpha=\frac{\text{opposite leg}}{\text{hypotenuse}}.`

Hence,

`\sin 50^(\circ)=(x)/(12)\Rightarrow 0.766=(x)/(12).`
