**Trigonometry (Question)**

- If sin x = 4/5 and cos x = 3/5, what is the value of tan x?
- If tan x = 12/5 while cos x = 5/13, what is the value of sin x?
- If tan x = 0.75 and the adjacent length is 10cm. What is the length for the hypothenuse?

*Guide: *

*sin x = t/hcos x = s/htan x = t/st – opposite sides – adjacent sideh – hypotenuse*

**Trigonometry (Answer)**

- 4/3
- 12/13
- 12.5cm
