Continue to next subchapter

Exercise 22 Page 44

∠ LMN is the angle created by the rays ML and MN.

108^(∘)

Practice makes perfect

The expression m∠ LMN tells us to find the measure of the angle between two rays, ML and MN. We have marked this angle in the figure below.

To find m∠ LMN, we must add m∠ LMP and m∠ NMP. m∠ LMN=85^(∘)+23^(∘)=108^(∘)
