Question

1. What is the sine ratio of ∠C?

A. 5/13
B. 5/12
C. 12/13
D. 13/12

2. What is the cos ratio for ∠C?
A. 8/10
B. 10/6
C. 10/6
D. 6/10

Answer 1

1. Sine ratio of angle ∠C = 12/13

2. cos ratio for ∠C = 6/10

Explanation:

1. sin = perpendicular /hypotuse

=> 12/13

2. cos = base / hypotuse

=> 6/10
