Answer:
4/3 = tan A
4/5 = sin A
3/5 = cos A
Explanation:
Define the adjacent, hypotenuse, and opposite lengths in the triangle.
Hypotenuse: 20
Opposite: 18
Adjacent: 12
Tan, sin, and cos formulas:
- Tan A = opposite/adjacent
- Sin A = opposite/hypotenuse
- Cos A = adjacent/hypotenuse
I think it should be pretty easy to do the rest by simplifying the fractions and then getting the answer!
Have a lovely rest of your day/night, and good luck with your assignments! ♡
