Question 4

expand »
a mountain climber begins climbing from a camp 2000 feet above sea level. she climbs 150 feet higher every hour. how many hours would she take to climb to 3650 feet above sea level?

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
