Question

Answer as quickly as possible​

Answer 1

Answer:

Solution given:

2:centroid=$\frac{x_1+x_2+x_3}{3},\frac{y_1+y_2+y_3}{3}$

=$\frac{1+3+5}{3},\frac{2+7+3}{3}=(3,4)$

4:

Slope:$\frac{y_2-y_1}{x_2-x_1}=\frac{6-2}{5-3}=2$

3;

perpendicular distance =$\frac{ax_1+by_1+c}{\sqrt{a²+b²}}$

$(x_1,y_1)=(3,-2)$

4x-3y+2=0

comparing above equation with ax+by+c =0 ,we get

a=4

b=-3

c=2

d=$\frac{4*3+(-3*-2)+2}{\sqrt{4²+(-3)²}}$

=4 units
