Question

I need this problems solved.​

Answer 1

Find the value of each trigonometric ratio in BOTH fraction form, and decimal form.

9) Tan X = 40/9 = 4.44...

10) Cos C = 8/17 = 0.47...

11) Sin Z = 14/50 = 0.28

12) Sin A = 21/29 = 0.72...

Find the missing side of each triangle. Leave your answers in simplest radical form. Then find the value of the given trig ratio in simplest radical form: Rationalize the denominador if nedd be.

13) x = √208, → Sin A = 8/√208 = 8/4√13 = 2/√13

14) x = √12 , → Cos A = 2√2/√12 = √2/√3

15) x = √80 , → Cos A = 4/√80 = 1/√20 = 1/2√5

16) x = √8 , → Tan A = 2√2/√8 = √2/√2 = 1

Good luck!! It was a pleasure to help you!
