What is the measure of ∠L? A right triangle L M N. Angle M is marked as a right angle. Side L M is labeled as 18 inches. Side L N is labeled as 60 inches.

72.54°

Step-by-step explanation:

Given that triangle LMN is a right-angle triangle and LM=18 inches and LN = 60 inches then;

applying the cosine rule

cos ∠L=Adjacent/hypotenuse

cos∠L=18/60

cos∠L=0.3

cos⁻¹ ∠L = 72.54°
