Question

Find the value of X...

Also, Could someone tell me when you use sin-1 and sin( ?

Answer 1

sin = opposite / hyptoenuse
sin 38 = 17/x

Switch them:

17/x = sin 38

Use a calculator to find sin 38

17/x = .296

Now, mulitply by 17 to get x alone

x = 5.04

Hope this helps :o)

Answer 2

When I do sin38 I get .615
