Question

two vertices of triangle are (8,-6) and (-4.6).The area of the triangle is 120 sq units .Find the third vertex if it lies on x-2y=6

Answer 1

Answer:

Step-by-step explanation:

apply formula det {x1-x2 x1-x3 =area

                             y1-y2 y1-y3}

by this you get equation

x-y=8

and question has equation x-2y=6

on solving these two equations

x=10 and y=2
