You can indeed use similar triangles to get a side of another similar triangle.
let's say Edwardo stood next to the building and his shadow was 20ft, he's 4ft tall, and the building cast a shadow of 125ft, then, check the picture below.
It would be 250 in because you see 10x20 is 200 and and 10x10 is 100. But since part of the figure is a triangle you have to dive it by 2 and 100/2=50. 200+50=250
Hope that helps!
B is not proportional because it does not go thru the origin
Answer:
D) 3 X 10⁷
Step-by-step explanation:
<u>Estimated days:</u>
- Jan 2000 to June 2001 = 1.5 years = 365*1.5 days ≈ 548 days
- 1 day = 24 hours = 24*60 minutes = 24*60*60 seconds =
- 548 days = 548 * 86400 seconds =
Best estimate is D) 3 X 10⁷
