Question

A right triangle has side lenghts 5, 12, and 13 as shown below. Use these lenghts to find sinA, tanA, and cosA

Answer 1

Answer:

sin A = 5/13

tan A = 5/12

Explanations:

From the Right-angled triangle shown:

Hypotenuse = 13

Opposite = 5

Adjacent = 12

sin A = Opposite / Hypotenuuse

sin A = 5/13

tan A = Opposite / Adjacent

tan A = 5/12

cos A = Adjacent / Hypotenuse

cos A = 12/13
