What is the height of this triangle? We have a triangle with sides 50, 70 and 80 and have drawn an altitude ('h') to side AB. We have segmented side AB into "x" and "80-x".
From the Pythagorean Theorem, we know that
h^2 = 50^2 - x^2 and that h^2 = 70^2 - (80 -x)^2
Both equations = h^2 so we can make a new equation
50^2 - x^2 = 70^2 - (80 -x)^2 which equals
2,500 -x^2 = 4,900 -6400 +160x -x^2
4,000 -x^2 = 160x -x^2
-2x^2 -160x +4,000 = 0

step-by-step explanation:

the one that has a slope of 1/2 and is positive.

step-by-step explanation: 2 buckets 1 trip ; 4 buckets 2 trips and so on.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
