Answer:

1) 68° 43'

2) 99° 10' 35"

Step-by-step explanation:

We know that two angles are complimentary if they sum up to 90°

Let compliment of 21° 17' be x.

Thus, 21° 17' + x = 90°

x = 90° - 21° 17'

Since 1° = 60',

x = 68° 43'

Two angles are supplementary if they sum up to 180°.

Let supplement of 80° 49' 25" be y.

Thus, 80° 49' 25" + y = 180°

Since 1' = 60",

y = 99° 10' 35"

Answer:

Answer is 68° 43'

Step-by-step explanation:

First we have to know what complement is , they are two or three numbers that add up to 90 so the first thing we should do is to :

21° 17' = 90°

=90°- 21° 17'

=90° 00'-21° 17'

So we have to subtract 9000-2117

Answer = 68° 43'

Hope it helps you
