## anonymous one year ago The vertices of a triangle are A(7, 5), B(4, 2), and C(9, 2). What is m∠ABC

1. abb0t

Well, m is midpoint, yes?

2. anonymous

yes

3. abb0t

To find the midpoint of each, you would have to do it from AB, BC, and AC. So use: $$\large \sf \color{red}{\frac{( x1 + x2)}{ 2} , \frac{( y1 + y2 )}{2}}$$

4. abb0t

Do the same for BC, and AC.
