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°

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
