The answer is 20%.
Step 1: Subtract the measured distance and the actual distance to calculate the error.
Step 2: Divide the given value by the actual distance and convert it into the percentage.
the actual distance is 612 ft
the measured distance is 735 ft
Step 1: 735 ft - 612 ft = 123 ft
Step 2: 123 ft / 612 ft = 0.20 = 20/100 = 20%
Think of it like a triangle.
The flagpole is vertical and is at 90° to the ground. This makes a right-angle to the ground, which is flat.
Since we have two sides of the triangle already, and they are in a ratio of ?? : 16 : 20 = ?? : 4 : 5, that means that because the triangle is a right-angled triangle, the third and last side must be 3 to complete the ratio! (This is called 'Pythagoras')
Since the other sides were divided by 4 to get the simple ratio, we must multiply 3 to get the actual ratio!
3 × 4 = 12 ft tall flagpole.

Answer:
0/16
Step-by-step explanation:
you use the equation y2-y1/x2-x1 so -12-(-12) which is 0 then do -18-(-2)=-16 so the slope is 0/-16
