Answer: Squares have all 4 sides equal. Just square root 180 in a calculator and you'll get √(180)= approximately 13.4.
Each friend would have taken a total of 35 rides each.
This can be verified by multiplying 35 by 35 to get 1225.

(Eq. 1)
(Eq. 2)
Since the difference between two even numbers leads to another even number. Hence, 
must be an even number and the correct answer is B.
Answer:
<h3>132°</h3>
Step-by-step explanation:
If line PS has midpoint a Q and ray QR, then line PQS will be a straight line and <PQR + <RQS = 180 (sum of angle on a straight line).
Given
<PQR = 3x-6
<RQS = x+ 2
To get x, we will use the relationship above;
3x-6+x+2 = 180
4x-4 = 180
add 4 to both sides
4x-4+4 = 180+4
4x = 184
x = 184/4
x = 46
Since <PQR = 3x-6, we will substitute the value of x into the formula;
<PQR = 3x-6
<PQR = 3(46)-6
<PQR = 138-6
<PQR = 132°
Hence the size of angle PQR is 132°
