If angle A has a measurement of 42° and is complementary to angle B, what's the measure of angle B?
138°, 48°, 38°, 42°
Solution:
Two angles are complementary angles when they sum up to 90°.
If angle A and B are complementary angles, then
A + B = 90°
A = 42°
Substituting the value we get
42° + B = 90°
By further calculation
B = 90° - 42° = 48°
Therefore, the measure of angle B is 48°.
If angle A has a measurement of 42° and is complementary to angle B, what's the measure of angle B?
138°, 48°, 38°, 42°
Summary:
If angle A has a measurement of 42° and is complementary to angle B, the measure of angle B is 48°.
