Find cosθ, secθ, and cotθ, where θ is the angle shown in the figure.

Question

cosθ =



secθ =

cotθ =

the hypotenuse side is 9

the other side is 4

the base is empty

the θ is at the bottom between the hypotenuse and base

Give exact values, not decimal approximations. 

Answer 1

Find the base using Pythagorean Theorem Base =sqrt(9²-4²)

Now just use the definitions of all the trig functions like sine(theta) = opposite side / hypotenuse...
