A climber is descending at a rate of 345 feet per hour. What is the climber's change in altitude after three hours of climbing?​

1035 feet in 3 hours

1035 Feet

Step-by-step explanation:

my mistake for not putting feet*

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.
