Answer:
Step-by-step explanation:
We have been given that ∠A and ∠B are complementary angles. The measure of angle A is degrees and measure of angle B is degrees.
We know that complementary angles add up-to 90 degrees, so we can set an equation as:
Therefore, the value of x is 20.
Therefore, the measure of angle A is 65 degrees.
Therefore, the measure of angle B is 25 degrees.

P(getting blue marbles) = 7/9
so;
x/45 = 7/9
x = 35
so the number of blue marbles is 35
45 - 35 = 10 red marbles
