Answer:

68.85 (rounded to nearest hundreth)

Step-by-step explanation:

Use the Law of Sines

Sin 56/4 = sin x/4.5

Now solve for x

4.5 sin56 = 4 sinx

sinx= (4.5 sin 56)/4

sin x = 0.9326672691

Inverse sin (0.9326672691) = 68.85448584

This is my answer I’m not sure what the answer choices are

180-56x2=68

x=68
