Answer:
The value of sin is : 12/13
Step-by-step explanation:
The formula for cosine of an angle is the length adjacent to that angle divided by the hypotenuse.
This means if ;
cos∅ = A/H
then using this information and given that;
cos ∅ = 5 by 13
cos ∅ = 5/13
You can find the opposite side length from Pythagorean relationship as;
13²-5²=b²
144 = b²
√144 = b
12 = b
Opposite side length = 12
Sin ∅ = opposite side length / hypotenuse
Sin ∅ = 12/13
