A ramp is being used to unload the back of a truck. The bottom of the ramp is 12 feet from the truck and the top of the ramp is

lying on the back of the truck. If the back of the truck is 5 feet high, which of the following equations can be used to find the length of the ramp? 52 + b2 = 122 , 122 + b2 = 52,  52 + 122 = c2

Answer:

The correct option is 3. The required equation is 5^2+12^2=c^2.

Step-by-step explanation:

It is given that the bottom of the ramp is 12 feet from the truck and the back of the truck is 5 feet high.

Let the length of the ramp be c feet.

The given information forms a right angled triangle. Where bottom of the ramp  from the truck is base, height of the back of the truck is perpendicular and length of ramp is hypotenuses.

Base = 12 feet

Perpendicular = 5 feet

Hypotenuses = c feet

Using Pythagoras theorem,

Perpendicular^2+Base^2=Hypotenuses^2

(5)^2+(12)^2=c^2

The required equation is (5)^2+(12)^2=c^2.

Therefore option 3 is correct.

The slope of a line is the ratio of rise to run for any two points on a line. Is this a true statement? Explain in two to four s
Blizzard [7]

Answer:

True

Step-by-step explanation:

The slope is the ratio of rise to run for any two points on a line.

The rise is the change in vertical axis, y

Rise = y2 - y1

The run is the change in the horizontal axis, x

Run = x2 - x1

Slope is the ratio of both:

Rise / Run = (y2 - y1) / (x2 - x1)
