Describe three ways to determine the measure of segment YZ.

Question illustration
Answer:

Solve the equation where the sine of 30 degrees is equal to YZ/50. Solve 180 – (30 + 90) = 60 to find the measure of angle Z. Then use the cosine of Z to write and solve an equation. Use the 30°-60°-90° triangle theorem to find that YZ = 50/2.
