Question

#28: Find both the complement and the supplement of each angle measure.
#14: Find the measure of the 3rd angle of each triangle in which the measures of 2 angles of the triangle are given.

Explain & Show work so I better understand it more.

14. x degrees, (x + 20) degrees
28. (90 - z) degrees

My Answer: Are these the only answers for the problems?

14. (160 + 2x) degrees
28. (90 + z) degrees

Work:

For Problem 14:

180 - 20 = 160 ; x + 20 = 180 ---> x = 160

For Problem 28:

180 - (90 - z) = 180 - 90 - (-z) = 90 + z

Answer 1

do you know what mean complementary and supplementary angles ?
