Question

In triangle ABC, angle C is a right angle. Find the value of the trig function indicated. Find tan A if c = 17 and a = 8

Answer 1

tan A= 8/15

Explanation:

1. draw triangle where A and B are legs and C is hypotenuse
2. A=8 and C=17, meaning that you need to find B by using Pythagorean theorem (a^2+b^2=c^2)
3. 8^2+b^2=17^2
4. 64+b^2=289
5. b^2=225

6.
`√(b^2) =√(225)`

7. b=15

8. tan= opposite/adjacent

9. tan A=8/15

Answer 2
