Question

If angle a and angle b are supplemrntary angles then find angle a​

Answer 1

Step-by-step explanation:

If angle A and angle B are supplementary angles and angle A is 3 times as large as angle B find the measures of angle A and Angle B. if the angles are supplementary than their sum is 180 degrees. angle A is 3 time angle B, therefore angle A is 135 degrees. 135 + 45 = 180 therefore the angles are supplementary

Answer 2

If angle A and angle B are supplementary angles and angle A is 3 times as large as angle B find the measures of angle A and Angle B

if the angles are supplementary than their sum is 180 degrees.

A + B = 180

if angle A is 3 times as large as angle B, then:

A = 3B

equation becomes:

3B + B = 180

combine like terms to get:

4B = 180

solve for B to get:

B = 180 / 4 = 45

angle A is 3 time angle B, therefore angle A is 135 degrees.

135 + 45 = 180 therefore the angles are supplementary.

solution is angle A is 135 degrees and angle B is 45 degrees.
