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
⇒[tex]m \angle A = 4^{\circ} + m\angle B[/tex] .....[1]
It is given that: The two angles are complementary
By definition of complementary angles;
[tex]m \angle A+ m\angle B = 90^{\circ}[/tex] .......[2]
Substitute equation [1] into [2] we have;
[tex]4^{\circ} + m\angle B + m\angle B =90^{\circ}[/tex]
⇒[tex]4^{\circ} + 2 m\angle B =90^{\circ}[/tex]
Subtract 4 degree from both sides we have;
[tex]2 m\angle B=86^{\circ}[/tex]
Divide both sides by 2 we have';
[tex]m \angle B = 43[/tex]
Substitute in [1] we have;
[tex]m \angle A = 4 + 43 = 47^{\circ}[/tex]
Therefore, measure of each angles are:
[tex]m \angle A= 47[/tex] and [tex]m \angle B = 43[/tex]
