I think it is the second option, the first is not true since the angles are not equally split, which is the definition of a bisector. Same reasoning for why the third choice doesn't work, as well as the last one.

Which equation is equivalent to √x^2+81 = x+10

jeka57 [31]

Keywords:

equation, operations, equivalent, binomial, square root

For this case we have an equation in which we must apply operations to rewrite it in an equivalent way. We must start by raising both sides of the equation to the square. Thus, we eliminate the square root of the left side of equality and finally solve the binomial of the right side of equality.

So we have:

$\sqrt {x ^ 2 + 81} = x + 10\\(\sqrt {x ^ 2 + 81}) ^ 2 = (x + 10) ^ 2\\x ^ 2 + 81 = (x + 10) ^ 2$
