Trigonometric problems. Could someone help me with this? I’m confused.

Oduvanchick [21]

the answer is a) 0.29 bc of SOHCAHTOA if u didn’t learn this then i can see why u were confused but it’s asking for tan which is TOA tan= opposite/adjacent so look for T and find the opposite of that angle which would be 7 and the adjacent would be the number next to it which is 24 so do 7/24 and u get 0.29
