Let
A---------> the angle that is complementary to angle B

we know that
If angle A and angle B are complementary angles
then
A+B=90°------> A=90°-B
B=60°
so
A=90°-60°-------> A=30°

the answer is
30 degrees

Answer:

30°

Step-by-step explanation:

Value of angle b= 60°

We have to find the measure of angle that is complementary to angle b

Complementary angles are the pair of angles whose sum is 90°

Complement of b= 90°- b

Complement of b= 90°- 60°

Complement of b= 30°

Hence, the correct answer is 30°
