Find the perimeter of the triangle whose vertices are A(−1,−6), C(14,2), and B(8,−6)). Write the exact answer.

$$c=x_B-x_A=8-(-1)=9$$

$$a=\sqrt{(x_C-x_B)^2+(y_C-y_B)^2}=\sqrt{(14-8)^2+(2-(-6))^2}=10$$

$$b=\sqrt{(y_C-y_A)^2+(x_C-x_A)^2}=\sqrt{(2-(-6))^2+(14-(-1))^2}=17$$

$$P_△=a+b+c=10+17+9$$

$$P_△=36$$
