Aframe of width a surrounds a 5 by 7 inch photograph. find the expression that represents the area of the frame in terms of a. asap a. a 2 − 35 b. a 2 + 12a + 35 c. none of these d. 4a 2 + 24a e. a 2 + 12a

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.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

what is the original number? you forgot to add it.
