Question

A right triangle has side lengths 7, 24, and 25 as shown below.Use these lengths to find cosB, tanB, and sinB.

Answer 1

Trigonometric ratios for angle B:

`\sin B=(opp)/(hyp)=(24)/(25)`
`\cos B=(adj)/(hyp)=(7)/(25)`
`\tan B=(opp)/(adj)=(24)/(7)`Then, angle B has: sine 24/25, cosine 7/25, tangent 24/7
