Which did you include in your response?
Solve the equation where the sine of 30 degrees is equal to YZ/50.
Solve the equation where the tangent 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.
