Well there are 180 degrees in a circle, so the equation should look like this 180/45 and the answer is 4
hope this helps you :D

Answer:
The answers are as follows: 12 106 42
Step-by-step explanation:
Given: 
Using BODMAS rule (Bracket, Of, Division, Multiplication, Addition and Subtraction) we would calculate 
separately and 
separately and add them. So we have 
.
Now for the second question: 
. we would get 
Next, 
. This could be written as: 
. Hence the answers.
Slope-intercept form:
y = mx + b "m" is the slope
First i would isolate the "y" in the equation.
2x + y = 4 Subtract 2x on both sides
2x - 2x + y = 4 - 2x
y = 4 - 2x or y = -2x + 4
The given line's slope is -2.
For lines to be perpendicular, their slopes have to be the opposite/negative reciprocals (flipped sign and number)
For example:
slope is 2
perpendicular line's slope is -1/2
slope is -2/3
perpendicular line's slope is 3/2
The given line's slope is -2, so the perpendicular line's slope is 1/2.
