∠A and \angle B∠B are complementary angles. If m\angle A=(7x+28)^{\circ}∠A=(7x+28) ∘
and m\angle B=(8x+2)^{\circ}∠B=(8x+2)
∘
, then find the measure of \angle A∠A.

1.based of the diagrams what is the the value of x? 2.how would you verify your answer for x

Ameteorologist is studying the monthly rainfall in a section of the brazilian rainforest. she recorded the monthly rainfall, in inches, for last year. they were: 10.4, 10.3, 11.7, 11.1, 8.0, 4.4, 2.6, 1.8, 2.5, 4.4, 7.3, 9.5 fill in the missing values in the formula. what is the variance?

If x varies directly as y, and x = 7.5 when y = 10, find x when y = 4
