Question

Find sin angle∠ A.
A. 3/5
B. 4/5
C. 1
D. 5/4

Answer 1

Answer:

The answer is B.

Step-by-step explanation:

We can use right triangle ratios.

Recall SohCahToa, where:

$\displaystyle \sin(A)=\frac{\text{opposite}}{\text{hypotenuse}}$.

The opposite side (to angle A) is 8, while the hypotenuse is 10.

Thus, we have:

$\sin(A)=8/10=4/5$

The correct answer is B.
