We'll set up an equation for this by adding the two known angles that equals 180.

It will be:

m° + 66° + 52° = 180

66 + 52 = 118

118 = 180 and we'll subtract 118 from 180

180 - 118 = 62

So, your answer is m= 62°

Answer:

62 degrees

Step-by-step explanation:

step 1) Subtract the existing angles (which are 66 and 52) from 180

step 2) Plug the number you got as well as the two existing angles into the formula a + b + c = 180 to check your answer. If each of the three angles add up to 180 you have the correct answer.
