Question

The two vertices of a triangle are (6, 3) and (-1, 7) and its centroid is (1, 5). Then the third vertex is

Answer 1

By using Centroid Formula
We get
6+3+x/3 = 1
9+x= 3
x=3-9
=-6
Also,
3+7+y/3 = 5
10+y=15
y=15-10
=5
So the Coordinates of Third vertex be(-6,5)

Answer 2

See the pic
Down I have attached it
I have to write at least 20 words that's y
