Question

Check all that apply. If cosθ=15/17 then:

A. cscθ=17/15

B. sinθ=15/8

C. tanθ=8/15

D. secθ=17/15

I think that the answers are C. and D.

Please help and explain. Thank you!

Answer 1

Assign any angle in a right triangle as theta. If cos theta = 15/17 then, the the adjacent leg equals 15 and the hypotenuse equals 17. Using the Pythagorean theorem, you know that the third side equals 8.

Now you can solve for the other trigonometric functions. So you're correct! C and D are the answers.

I hope that helped :)
