Asked by DeeDee
A triangle has two angles, one 90 degrees, the other (between adjacent and hypotamuse) 26 degrees, and a hypotamuse of 10ft. Find the opposite side's length.
Hint: use sine.
I think I'm supposed to do 10(sine26), but the answer isn't right. What am I missing?
Thanks!

opposite side is 10sin26° , so you are correct
10sin26°
= 10(.43837...
= appr 4.38
make sure your calculator is switched to degrees and not radians
on most calculators , it will show DEG somewhere in your display. If you see RAD, look for a key DRG and press it repeatedly until you see the DEG.
You should then get my results.
