100 ft
y ft
x ft
Which system of equations can be used to determine y, the height above the ground at the top of the wall, and the horizontal distance
between where the wall begins and where it ends at ground level.
Recall the Pythagorean theorem, 2 + b2 = 2, where a and b are the side lengths of a right triangle, and is the length of the hypotenuse.
A. 1+ + y = 100
y = 3:
B. + y = 100
1 = = 3y
C -2 + y2 = 1002
1 * = 3y
D S2 + y2 = 1002
1y = 3:
