Qing attached a dog ramp to her bed, which allows her dog to easily climb onto the mattress. the ramp is 48 inches long. the base of the ramp is 40 inches from the base of the bed. how high off the ground is the top of the mattress? enter your answer, rounded to the nearest tenth, in the box.

Using the formula a^2+b^2=c^2you can fill in the numbers so that a=height of mattress in inches,b=40 inches or distance from base of the bed and c=48 or length of the ramp. a^2+40^2=48^2a^2+1600=2304
So then it becomes2304-1600=a^2704=a^2 26.5+=aSo, The top of the mattress(after rounding) is 26.5 inches off the ground.
