First, we should figure out exactly what a mode is.

What is the mode of a number set? The mode is the number that appears most often in a set. If they are all equal, there is no mode. If there are two, it is called bimodal, if there are 3 it is called trimodal, and if there are 4 or more modes, you would call it multimodal.

Now, we have to figure out which number is the mode of the numbers. We need to count each of the numbers. The easiest way on any laptop or computer is by doing CTRL+F, which would make it so you can find words or phrases and see how many times it repeats. I will leave out all of the numbers that do not repeat simply because they don't.

78 repeats 3 times and 43 repeats itself twice. Those are the only two that are in the system more than one, and we can see which one repeats the most.

Answer: The mode of the given number systems is 78, with it repeating 3 times.

1 and 2 are complementary angles. 1 and 3 are vertical angles. If

If angle 1 and angle 2 are complementary, then they add up to 90 degrees. We are given that angle 2 equals 52 degrees.

So we subtract and get our answer:

That's NOT the final answer.

The next step is:

Angle 1 and angle 3 are vertical angles.

Vertical angles are congruent.

So if angle 1 is 38, then angle 3 is also 38.

Now, supplementary angles add up to 180 degrees.
