Question

PLEASE HELP ME WITH THIS

In the accompanying diagram, m<A=32° and AC = 10. Which equation could be used to find x in ∆ABC?

1. x=10 sin [32°]
2. x=10 cos [32°]
3. x = 10 tan [32°]
4. x=10/cos32​​​

Answer 1

3.x=10tan[32]

Explanation:

Using SOHCAHTOA

PICK TOA i.e

TanX=Opp/Adj

Capital X i.e the angle = 32°

tan32=x(small)/10

cross multiple

x=10tan32

x=10tan[32]
