Step-by-step explanation:
(40×5)+(2×5) so 40×5=200 and 2×5=10 so 200+10=210
Complementary angles are those angles whose sum is 90 degree.
The measurement of two complementary angles are

There sum have to be 90 degree. That is

Combining like terms ,

Moving 20 to right side

Dividing both sides by 5

So the measurement of the angles are
