72. Sammy and Luis each threw a ball into the air at the same time. The height, in feet, of Sammy's
ball after t seconds is modeled by the expression
2 + 40+ – 16t2. The height, in feet, of Luis's ball
after t seconds is modeled by the expression
2 + 35t - 16t2. Which expression can be
evaluated to find how much higher Sammy's
ball is than Luis's ball after t seconds?

A 5t
B.5t +4
C 75t + 4
D -3212 + 75t + 4

step-by-step explanation:

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.

central angle of a triangle has the same measure as its intercepted arc.
