Answer:
The street light is 20 feet tall.
Step-by-step explanation:
This question depends on a proportion. Keep your height of the object in one ratio and the length of the shadow in the other.
25/x = 75/60 Notice the height of the structure is on the left. The length of the shadow is on the right. Cross multiply
75x = 60 * 25 Combine the right
75x = 1500 Divide by 75
x = 1500/75
x = 20
The street light is 20 feet tall.
XY is the rightmost side of the rectangle. Since you have the image already graphed, you can just <u>count</u> how many units there are from X to Y.
If you are starting at point X and you walk to point Y, how many "lines" do you cross to get there?
Answer: 4 units
3-5w+12+2w-3
(3+12-3)=12
(-5w+2w)=-3w
-3w+12
The side of the square is (12x+52)/4=3x+13.
