Homework Equations


a+b+c=180
[/B]


The Attempt at a Solution


So RP=RQ, the base angles are x and (146-x), normally the base angles are the same but in this scenario they are different.
x+146-x+?=180

Why do you say that x and 146-x are different? Wouldn't that depend on the value of x?

What's your solution ?
x+146-x+x=180
x+146=180
x=34,
180-34=146
146/2=73
x=73

x+146-x+x=180
x+146=180
x=73
Really? Check your algebra. Also, your equation is incorrect.
