Complementary angles are adjacent angles which add to equal 90 degrees (a right angle). To find m∠A in these figures, set the sum of the known angle measure and the unknown angle measure, A, equal to 90 and solve.
10)
90 = 67 + A
23 = A
m∠A = 23°
11)
90 = 57 + A
33 = A
m∠A = 33°
12)
90 = 44 + A
46 = A
m∠A = 46°

sorry for the late response it's c224
Since you didn't give an amount of time, we can't give an exact value. However, I can help you with the steps so you can get the correct answer.
First, you need to find the correct z-score. Then, use a standard normal distribution table to find the percent.
Let the time that you are looking for equal X.
The formula for your z-score is:
(x - 8.7) / 2.1 = z-score
-4a+3b You have to add all a's together and all b's ;)
