The answer is median, because the data is skewed and there is an outlier.
Answer:
(a) = 60
(b) = 70
Step-by-step explanation:
(a) Sum of all the angles of a triangle is 180
This is an equilateral Triangle
which means all the sides are equal since all the sides are equal that means all the angles are equal

(b) this is an isosceles triangle with two equal sides that means the two opposite angles are equal

Answer:
62.5.
Step-by-step explanation:
Given:
The expression to simplify is given as:
55 - 4.5 +12
We have to use PEMDAS method in order to simplify this.
P stands for parenthesis, E for exponents, M/D stands for Multiplication or Division and A/S stands for Addition or Subtraction.
P has the highest priority followed by E followed by M or D which ever comes first followed by A or S which ever comes first.
Here, the first operation we encounter is subtraction S.
First, we will subtract 4.5 from 55. So, 55 - 4.5 = 50.5
Next operation is addition A.
Now, we will add the result to 12. So, 50.5 + 12 = 62.5
Therefore, the answer is 62.5.
I think its he didnt eliminate the same variables
3/8 * 5/5 = 3/8 because 5/5 = 1
