Answer:
18° and 72°
Step-by-step explanation:
Complimentary angles form 90°
We have an angle (x) 4 times larger than the other (y).
Well actually, a system of equations isn't required, so forget about x and y, just divide 90 by 5. This gives you 18, one of the angle's measurements is 18°. Multiply 18 by 4 and get 72. The other angle's measurement is 72°.

Answer:
The provided statement is not a binomial experiment.
Step-by-step explanation:
Four conditions of a binomial experiment:
There should be fixed number of trials
Each trial is independent with respect to the others
The maximum possible outcomes are two
The probability of each outcome remains constant.
For example:
Binomial distribution: Asking 200 people if they ever visit to new york.
Not Binomial distribution: Asking 200 people how much they earn in a week.
Now, observe the provided information:
We need to determine that, asking 100 people which brand of car they drive is a binomial experiment or not.
Clearly it is not a binomial experiment because the maximum possible outcomes are not two.
Therefore, the provided statement is not a binomial experiment.
