Question

Give each trig ratio as a fraction in simplest form.

Answer 1

Explanation:

First, use the pythagorean theorem to complete the vales of each sides of the triangle. Then, use the respective trigonometric formulas and inverse the answer to compute the degree of every corners.

Answer 2

`df = \sqrt{ {29}^(2) - {20}^(2) } = 21 \\ \sin(d) = (20)/(29) \\ \cos(d) = (21)/(29) \\ \tan(d) = (20)/(21) \\ \sin(e) = (21)/(29) \\ \cos(e) = (20)/(29) \\ \tan(e) = (21)/(20)`
