# A 9.5-foot pole casts a shadow that is 29 feet long. What is the approximate measure of angle L? The triangle is JKL and K=90 degrees.

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.
