Let complementary angle be x,

Then the other angle is 4x

x + 4x = 90 ( complementary angles)

5x = 90

x = 90/5

x = 18,

The measure of the smaller angle = 18

And the measure of the larger angle = 4x

= 4 * 18

= 72

The supplementary of the larger angle is,

Let y be the other supplementary angle.


72 + y = 180 ( Supplementary angles)

y = 180 - 72

y = 108.

Hence, the other supplementary angle is 108 degrees.


Hope you understood. Plzzz let me know if you have any doubts.
