Please help, Geometry I have NO idea how to do this. Both Pictures! (#36, #37) WILL MARK BRAINLIEST!

1) The definition of a scalene triangle is that ALL sides are different.
Now, to prove a triangle is scalene, we need to show that all three sides output different values. Therefore, selections with only two sides certainly are insufficient. If we look at the last two choices, you can easily spot that the second to the last is correct answer by comparing the definition of a scalene triangle.
2) You will need to perform something similar to the previous questions, which is, find the distance between the three points, and see if they are all different => scalene; all the same => equilateral; or two of them are the same => isosceles.
The distance formula between two points (a, b) and (c,d) is given as:
Just for you to check your work, the distances between three points are:
sqrt(34), sqrt(17), sqrt(37), which results a scalene triangle.

Answer:
30%
Step-by-step explanation:
Before starting to solve this question we have to understand the following. 1% is equal to one hundredth of something whole, and can be write as .
Now in order to solve this question we will first have to find a fraction that represent how much student out of the whole class choose hamburgers. We can easily find this fraction since the numerator of the fraction will be equal to the number of people that choose hamburgers and the denominator will be equal to the number of all students in the class. So we get......
Now in order to find out what percentage will this fraction equal to we will have make a fraction with the same value but with a denominator being 100. To do that we will have to understand the following......
(m is any number except 0)
The main I idea of this rule is that if we multiply the numerator and the denominator by the same number (any number except 0) we will get a fraction with the same value but with a different denominator and numerator.
So in our case we we do the following.........
(multiply both numerator and the denominator by 10 and we get...)
Now if we go back to what I said at the start of my explanation we will understand that another way of writing down is 30%.
