Question: If A= 29 degrees and a= 4.6, find c.

There is a diagram shown in the textbook. b is adjacent, c is the hypotenuse, and a is opposite. I know I'm suppose to use SOH CAH TOA, and i tried using tan, but Im not getting the correct answer. i looked in the back of the textbook to check my answer and it was incorrect. The correct answer is 9.5. The answer I got was 2.5. In my calculator I pressed tan and 29, then i times 4.6. I dont know what im doing wrong, please help.

Following your description I got
sin 29° = opp/hyp = 4.6/c
csin29 = 4.6
c = 4.6/sin29
= 9.48826.. or appr 9.5

I don't know how you got 2.5
