Question

Find the measure of the complement and supplement of an angle measuring 90.2°.

-no complement, 90.8°
-no complement, 89.8°
-0.8°, 100.8°
-0.8°, 90.8°

Answer 1

89.8⁰

Explanation:

As its greater than 90 , no complement

Supplement = 180 - 90.2 = 89.8⁰

Answer 2

no complement, 89.8

Explanation:

Complementary angles add up to 90 degrees.

Therefore the complement of 90.2° is
`90\degree-90.2\degree=-0.2\degree`

From the options we can deduce that we are interested in only positive angles.

Supplementary angles add up to 180 degrees

Therefore the supplement of 90.2° is 180-90.2°=89.8°

The second choice is correct
