Answer:

x=69.41860973

Step-by-step explanation:

We can use the law of sines

sin x             sin 55

------------- = -----------

4                       3.5

Using cross products

3.5 sin x = 4 sin 55

Divide each side by 3.5

sin x = 4/3.5 sin 55

Take the inverse sin of each side

x = sin ^-1 ( 4/3.5 sin 55)

x=69.41860973
