Trig functions Question

[Guest]

Find the exact value of each of the five other trig functions for the angle (without finding the angle) given the indicated info.

(Sin angle = 3/5.)

I know the trig functions. But using the reference triangle I need to find the value of coordinate (a) to complete the other five functions. What steps do I take?

What steps do I take?

Draw a right trangle.

Label the "opposite" and "hypotenuse" sides appropriately.

Apply the Pythagorean Theorem to find the third side's length.

Read off the values of the other five trig functions.
