Set up your equation to find the measure of angle A.

• sin A / 29 = sin 50 / 37
• sin 37 / A = sin 29 / 30
• sin A / 37 = sin 50 / 29
• sin A / 37 = sin 29 / 50

Now that you have your equation
sin A / 37 = sin 50 / 29
Get the sin A alone.

• 0.123
• 0.865
• 0.766
• 0.977

Now that you're down to
sin A = 0.977
how should you get A alone?

• sin^-1 (called inverse sine)
• cos^-1 (called inverse cosine)
• take sin 0.977
• take cos 0.977

What is the measure of angle A?

• 50 degrees
• 60 degrees
• 78 degrees
• 74 degrees
