Find the complement of 75∘
When the sum of 2 adjacent angles is equal to 90∘ they are called complementary angles. 75∘+angle=90∘∴angle=90∘−75∘=15∘∴complement of 75∘ is 15∘
Find the measure of the angle whose complement is 75∘.
The measure of an angle is five times its complement. The angle measures
(a) 25∘
(b) 35∘
(c) 65∘
(d) 75∘
