Question

1. If the area of a triangle formed by (x, 2x), (-2, 6) and (3, 1) is 5 square units, then find the value
of x​

Answer 1

Answer:

x=5/3

Step-by-step explanation:

area of the triangle =x1(y2-y3)+x2(y3-y1)+x3(y1-y2)

5 =x(6-1)-2(1-2x)+3(2x-6)

5 =5x-2+4x+6x-18

5 =15x-20

15x = 25

x=25/15

=5/3
