Hey there!
First, let's find c, our hypotenuse. We will use the sine.
sin22≈0.37
This gives us the equation below.
0.37=7/c
0.37c=7
c≈18.92
Now, let's find b. We will use the tangent, as it deals with both legs.
tan22≈0.4
This gives us the equation below.
0.4=7/x
0.4x=7
x=17.5
This gives us our answers below.
b= 17.5 (Leg)
c≈ 18.92 (Hypotenuse)
I hope this helps!
