A homeowner is to construct a ramp to their front door to make the house wheelchair accessible. What must the angle of elevation of the ramp be for the
ramp to be 15 feet long and reach the front door that is 3 feet high? (In your
answer, round to the nearest degree. For example, 58.8 becomes 59, and
60.34 becomes 60.)

answer: your correct answer is b. d.

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

y-3=-3/2(x+4)

ur very much welcome
