Answer:B is the correct option
Explanation:
Triangle ABC is a right angle triangle. This is because one of its angles is 90 degrees. The unknown side AB can be determined using Pythagoras theorem. It is expressed as
Hypotenuse^2 = opposite^2 + adjacent^2. Therefore
8^2 = AB^2 + 7^2
AB^2 = 64 - 49 = 15
AB^2 = √15
To determine SinC, we would apply trigonometric ratio
SinC = opposite / hypotenuse
Opposite = √15
Hypotenuse = 8
SinC = √15/8
