A45 foot long escalator rises from the first floor to the second floor of a shopping mall. the escalator makes a 30° angle with the horizontal. how high above the first floor is the second floor?
a. 26 ft
b. 78 ft
c. 22.5 ft
d. 45 ft

It's a 30-60-90 triangle, the side opposite the 30 degree angle is half of the hypotenuse. So the answer is C.22.5

can you make your screen more see able?

then i might be able to .

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
