Which point lies on the circle x^2+y^2=100
A (0,-100)
B (10,-10)
C (25,75)

NOT a single ordered pair satisfies the equation.

Step-by-step explanation:

Given the equation

Let us substitute all the given ordered pairs to find which ordered pair satisfies the equation.

For (0, -100)

substitute x=0 and y=-100

FALSE

Thus, the ordered pair (0, -100) does NOT satisfy the equation.

For (10, -10)

substitute x=10 and y=-10

FALSE

Thus, the ordered pair (10, -10) does NOT satisfy the equation.

For (25, 75)

substitute x=25 and y=75

FALSE

Thus, the ordered pair (25, 75) does NOT satisfy the equation.

Therefore, NOT a single ordered pair satisfies the equation.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
