Answer:
172.5
Step-by-step explanation:
Use similar triangles and a proportion.
(tree height)/(tree shadow length) = (your height)/(your shadow length)
x/(270 ft)= (5 ft 9 in.)/(9 ft)
x/(270 ft)= (5 ft + 9/12 ft)/(9 ft)
x/(270 ft)= (5.75 ft)/(9 ft)
9x = 270 * 5.75 ft
x = 30 * 5.75 ft
x = 172.5 ft
Answer:
B. x=75
Step-by-step explanation:
First, write out the equation as you have it:
x/5=15
Then, multiply both sides of the equation by 5/1:
5/1(x/5)=15(5/1)
Your result is:
x=75
