Question

(23) Find the sine of Angle R. Reduce the answer to the lowest terms.

Answer 1

sinR = Opp / Hypo = 8/10
sinR = 4/5

Answer 2

Since sine is equal to opposite over hypotenuse, you would create the fraction 8/10. 8 and 10 are both divisible by 2, so that fraction would reduce to 4/5, which is the answer.
