Q
Q: If angle A is 30 degrees and angle B is its complement, what is the measure of angle B?
Solution:
The complement of an angle is found by subtracting it from 90 degrees. Thus, angle B = 90 - 30 = 60 degrees.
Steps: 6
Show Steps
Step 1: Understand that the complement of an angle is what you need to add to it to make 90 degrees.
Step 2: Identify the measure of angle A, which is given as 30 degrees.
Step 3: Use the formula for finding the complement: Complement = 90 degrees - angle A.
Step 4: Substitute the value of angle A into the formula: Complement = 90 - 30.
Step 5: Calculate the result: 90 - 30 = 60 degrees.
Step 6: Conclude that angle B, which is the complement of angle A, measures 60 degrees.
