Question

Given right triangle RST, what is the value of sin(S)?

A) 5/13

B) 5/12

C) 12/13

D) 13/12

Answer 1

the correct answer is 5/13 letter A..

Answer 2

Option A is right

Answer= 5/13

Given a right triangle RST.

The triangle is right angled at R

The hypotenuse is 13 and legs are 5 and 12.

We have to find the value of sine of S

We know by definition sin of any angle = opposite side/hypotenuse

Hence sin S = opposite side/Hypotenuse.

S has opposite side as 5 and hypotenuse as 13.

So sin S = 5/13

Option A is right.
