Hello from MrBillDoesMath!
Answer:
66
Discussion:
Q and R are complementary angles means that
Q + R = 90. If Q = 24, then
24 + R = 90 => subtract 24 from both sides
24 - 24 + R = 90 - 24 =>
R = 66
Note: complementary is the proper spelling of the word. Complimentary. with an "i", relates to an expression of praise. Different words entirely.
Thank you,
MrB
