Question

In ΔRST, the measure of ∠T=90°, TS = 9, RT = 40, and SR = 41. What ratio represents the sine of ∠R?

Answer 1

sn R=9/41

Explanation:

hypotenuse is side opposite to 90 degree.So,here hypotenuse is RS

side opposite to angle R is perpencicular (opposite) is side TS

ratio of sin of angle R is

sin R=opposite/hypotenuse

=TS/RS

=9/41
