Answer:
Maybe if you added a coordinate chart someone could actually help you :)
Step-by-step explanation:
0.7 Is An Irrational Number, Not A Rational Number
4^2 + b^2 = 12^2
16 + b^2 = 144
B^2 = 144-16
B^2 = 128
B= 11.3
Let's solve for the answer to determine if it is rational.
it is a rational number.
