Question

I don't get this question i need some help please!!!

Answer 1

Answer: D

Use sine to find the x-value:

`sin(45)=(x)/(4) \\\\4*sin(45)=x\\\\x=(√(2) )/(2) *4=2√(2)`

Answer 2

2 sqrt(2) = x

Explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp / hyp

sin 45 = x/4

4 sin 45 = x

4 ( sqrt(2)/2) =x

2 sqrt(2) = x
