In VWX and PQR similar? How do you know?

This triangle is not a right triangle. How do we solve this then? You will use the law of sine with is shown below:

What we know is shown in the image attached below:

Plug what you know into the law of sine

To solve for sinB cross multiply

sin75*33.7 = sinB * 51.2

32.55 = sinB*51.2

Divide 51.2 to both sides to isolate sinB

32.55 / 51.2 = sinB / 51.2

0.63577 = sinB

To find B you must use arcsin:

39.477

^^^This is your rough estimate but you can simply keep it to 39 degrees

This means that your answer is correct!

Hope this helped!
