Question

Solve for x. Round to nearest tenth. Picture attached, trigonometry. Will give a medal and fan to anyone who helps, forgot how to do this!!

Answer 1

use sine

sine is opposite/hypotenuse
so sin 35 = x/20
x=20sin35
x=11.47

Answer 2

Thanks! I'm trying to solve another one too so maybe you can check my work when I am done?

Answer 3

I came across this is anyone can help me?? It has two angles in it, would you still solve it the same way? How would I set that up, thanks!

Answer 4

use sine but this time the angle is 28 degrees
so opposite/hyp
sine 28=50/x
x=50/sine 8
x=106.5

Answer 5

Thank you! This has helped me a lot I understand better now :)
