Question

Solve the right triangle round your answers to the nearest tenth a equals 12.2 b = 14.6 and c equals 19 with 50° angle. Solve for A

Answer 1

Answer: <A= 66.5 degrees

Explanation:

sinA/14.6=sin(50)/12.2

Cross multiply so 12.2(sinA)=14.6(sin50)

So get sinA on a side by itself

sinA=14.6sin(50)/12.2 (so enter this into your calculator) the answer you should get is .91674171

Now we have to do the inverse to find the angle so sin^-1(.91674171)
