16.Calculate
a. 7 over square root of 13
b. 6 over square root of 13
c. 6 over square root of 85

Answer 1

Sine - Opposite over Hypotenuse
Cosine - Adjacent over Hypotenuse
Tangent - Opposite over Adjacent

Answer 2

Since it's a right triangle, apply pythagorean's theorem to find the hypotenuse; \(6^2+7^2=c^2\\c=\sqrt{85}\)

Answer 3
