Question

Ok, I found out how to find complementary angles. But now I learned out how find supplementary angles. I have homework that is due tomorrow and I forgot my notes from today, someone please help me find this angle asap!

Answer 1

∴ x = 5

Explanation:

(18x)° = 180° - 90° (adjacent angles on a straight line)

18x = 90

∴ x = 5
