The measure of A is 75°, and the measure of B is 105°. What is the relationship of angles A and B?

They are supplementary angles.

Step-by-step explanation:

Supplementary angles are two angles that add up to 180°

105+75=180

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

a
