The measure of A is 4 degrees greater than the measure of B. The two angles are complementary. Find the measure of each angle

Verified Answer :

angle B =X
angle A = x+4
complementary angles= 90 degrees

x+x+4= 90
2x= 86
x= 43 degrees for angle B
43+4 = 47 degrees for angle A

Hope this helps

Answer:

Two angles are said to be complementary angles if the sum of the measure of angles is 90 degree.

As per the statement:

The measure of A is 4 degrees greater than the measure of B

⇒\(m \angle A = 4^{\circ} + m\angle B\)       .....[1]

It is given that:  The two angles are complementary

By definition of complementary angles;

\(m \angle A+ m\angle B = 90^{\circ}\)       .......[2]

Substitute equation [1] into [2] we have;

\(4^{\circ} + m\angle B + m\angle B =90^{\circ}\)

⇒\(4^{\circ} + 2 m\angle B =90^{\circ}\)

Subtract 4 degree from both sides we have;

\(2 m\angle B=86^{\circ}\)

Divide both sides by 2 we have';

\(m \angle B = 43\)

Substitute in [1] we have;

\(m \angle A = 4 + 43 = 47^{\circ}\)

Therefore, measure of each angles are:

\(m \angle A= 47\) and \(m \angle B = 43\)
