Hi there! Hopefully this helps!

Question A answer: 2.
To find the <u>median</u>, you simply need to order the set from lowest to highest and finding the <u><em>exact middle</em></u>. So it should look like this:
0, 1, <em><u>2</u></em>, 3, 4. So 2 is the median, therefore 2 is the answer to Question A.
------------------------------------------------------------------------------------------------
Question B answer: 2
To find the <u>mean</u>, you have to add all of the numbers together and then you have to <u>divide by the number of items in the set</u>. There are 5 numbers in the set so it should look like this:
0 + 1 + 2 + 3 + 4 = 10.
Since there 5 numbers in the set, we need to divide by 5.
10 / 5 = 2.
Therefore, 2 is also the answer to Question B.

Answer:
70°
found by considering A-frame ladder as a triangle
Step-by-step explanation:
Given that,
angle form on either side of A-frame ladder with the ground = 125°(exterior)
As it is a A-frame ladder so its a triangle, we will find the angle at the top of ladder by using different properties of triangle
1) find interior angle form by A-frame ladder with the ground
125 + x = 180 sum of angles on a straight line
x = 180 - 125
x = 55°
2) find the angle on top of ladder
55 + 55 + y = 180 sum of angle of a triangle
110 + y = 180
y = 180 - 110
y = 70°
9.88 • 10°
