Answer:
m∠1 = 85°, m∠2 = 85°, m∠3 = 64°, m∠4 = 31°
Step-by-step explanation:
1. Since ∠3 and the angle labeled 64° are vertical, they are congruent, therefore m∠3 = 64°
2. By the same logic, since ∠4 and the angle labeled 31° are vertical, they are also congruent, meaning m∠4 = 31°
3. ∠4, ∠1, and 64° make up 180°, thus a straight line around them, so m∠1 + 31° + 64° = 180° --> m∠1 = 85°
4. ∠1 and ∠2 are vertical, so they are congruent, meaning m∠2 = 85°
The unknown side is part of the 90 degree angle, so it is not the hypotenuse.
Using the Pythagorean theorem:
x = sqrt(14^2 - 10^2)
x = sqrt(196-100)
x = sqrt(96)
x = 9.7979 ( round as needed)
The answer is attached. I hope this helps answer your question!

1 - B
Mode - The mode the number that appears most often in a data set. In this question, 25 was repeated 3 times and no other ones where repeated 3 times. Thats why 25 is the mode.
2 - D
Median - The middle number of a data set that is arranged from least to greatest.
3 - True
There is no mode because all of the numbers only appear once.
4 - A
5 - C
