Choose the statement that is true and has a converse that is also true.

A. If a line has the equation y = 3x + 2, then the slope of the line is 3.
B. If x^2 = 100, then x = 10.
C. If x − 1 = 8, then x = 9.
D. If an angle measures 45 degrees, then the angle is acute

if x^2 = 100 
square root both sides 
x = +/- 10 
because (-10)^2 is also 100

so its? 
i am not good at math

nincompoop · Answer

first, what is a converse?

nincompoop · Answer

second, gather everything that is true
I already eliminated one of the choices for you.
