Answer:
81 and 9
Step-by-step explanation:
Okay, so if 2 angles are complementary, it means that when they are added together, they equal 90 degrees. So using this, we can make an equation. Let's call one angle x and the other that is 72 less than angle x can be described as x - 72. Now let's make that into an equation.
90 = x + x -72
So in order to solve this, we need to get x by itself. So we need to add 72 on both sides, and the equation should now look like this:
162 = x + x
Now we have to add the x's together.
162 = 2x
Now in order to isolate x, you divide by 2 on both sides.
X = 81
So we now know the larger angle is 81, and the smaller angle which is 72 less, would be 9.
Answer:
Stratified sampling
Step-by-step explanation:
The is a type of sampling in which the population of interest is divided into subpopulations and then each subpopulation is randomly sampled.
In this case study, instead of just doing a random sampling of all students, the research divided the population of all students into subpopulations which includes freshmen, sophomores, juniors and seniors and then she makes a random sampling of each of these subpopulations.
