Question

Evaluate the function requested. Write your answer as a fraction in lowest terms.How do we do this equation? Find Sin A

Answer 1

Answer: sin (A) = 4 / 5

Procedure step-by-step:

1) The ratio sine is defined as opposite-leg / hypotenuse

2) From the figure, the opposite-leg to angle A is BC and it measures 28

3) From the figure, the hypotenuse is AB and its measure is 35.

4) Therefore sin(A) = 28 / 35.

5) Simplify dividing numerator and denominator by 7: 28 / 35 = 4 / 5
