Question

What is the measure of L in

degrees? Round your answer to
the nearest hundredth.
23
N
18

Answer 1

Use trigonometry to find L.

Tangent = opposite over adjacent on any right triangle.

tan(L) = 18/23

Take the inverse on both sides.

arctan(tan(L)) = arctan(18/23)

L = 38.0470425318

L = 38.05°

Done.
