Find the angle complementary to the angle 80°25′.

a. 90°
b. 99°35′
c. 180°
d. 9°35′

Two angles are said to be complementary to each other when the sum of the two angles gives 90°. To find the angle complementary to angle 80°25′, we subtract angle 80°25′ from angle 90°. i.e. 90° - 80°25′ = 90° - 80° 25/60 = 90° - 80° 5/12 = 9° 7/12 = 9° (7/12 x 60)' = 9°35' Therefore, the angle complementary to 80°25′ is 9°35'.

The answer is 95 minutes.

Step-by-step explanation:

1. Convert 6 hours to minutes which would lead to 360 minutes.

2. 360 minutes + 20 minutes = 380 minutes.

3. Now find 25% of 380 minutes.

How I found 25%.

1. 50% of 380 = 190.

2. 50% of 190 = 95.

Now since the half of our base half is 95 then 2 halfes are 2 25% but we need 1 only so we can conclude that, 25% of 380 minutes is 95.

Hope this helped :).
