Angle A and angle B are complementary angles. If angle A =(2x+30) and angle B=(7x-3), then find the measure of angle B

both equations and proportions are better.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
