Answer:
x=7.12
Step-by-step explanation:
This is a trigonometry problem so you would use sin cos or tan. and in this case we need to use sin.
An acronym I use to help me remember is is sohcahtoa
so sin= opposite / hypotenuse
and that means sin(22)= x/19
we then plug in sin (22) in out calculator and get around .37
then we can use algebra and multiply .37 by 19 to get our x value
.37(19)=x
