Question #50a30

Answer 1

Angle B - Angle A = 6 degrees.

Explanation:

Supplementary angles add up to 180 degrees. If the supplement of angle A is 138 degrees, then 180 degrees - 138 degrees will give you angle A.

`180 - 138 = 42` degrees.

Complementary angles add up to 90 degrees. If angle B is the complement of angle A, then 90 degrees - 42 degrees will give you angle B.

`90 - 42 = 48` degrees.

Angle B - Angle A

-> `48-42=6` degrees.
