Directions: Find the complemen
andre [41]

Given:

The angles are:

Example 54^\circ

1. 63^\circ

2. 87^\circ

3. 45^\circ

4. 72^\circ

5. 5^\circ

To find:

The complimentary angle of the given angles.

Solution:

If two angles are complimentary, then their sum is 90 degrees.

Example: Let x be the complimentary angle of 54^\circ, then

x+54^\circ=90^\circ

x=90^\circ -54^\circ

x=36^\circ

Similarly,

1. The complimentary angle of 63^\circ is:

90^\circ -63^\circ=27^\circ

2. The complimentary angle of 87^\circ is:

90^\circ -87^\circ=3^\circ

3. The complimentary angle of 45^\circ is:

90^\circ -45^\circ=45^\circ

4. The complimentary angle of 72^\circ is:

90^\circ -72^\circ=18^\circ

5. The complimentary angle of 5^\circ is:

90^\circ -5^\circ=85^\circ

Therefore, the complimentary angles of 54^\circ, 63^\circ, 87^\circ, 45^\circ, 72^\circ, 5^\circ are 36^\circ, 27^\circ, 3^\circ, 45^\circ, 18^\circ, 85^\circ respectively.
