Question

Hi! So I am stuck on three problems right now, can you Please help me?number 1, says "What is the cosine ratio of

Answer 1

The cosine ratio is given by the following formula:

`\cos (Z)=\frac{\text{adjacent leg}}{hypotenuse}`

The adjacent leg of angle Z is side ZY=12 and the hypotenuse of the triangle is the side XZ=20, thus the cosine ratio of Z is:

`\cos (Z)=(12)/(20)`
