1.	The area of a traingle with vertices (6,-3),(3,k) and (-7,7)is 15 sq.units.find the value of k
Answer» Answer: The value of K is 21/13units or -3 UNITS. Step-by-step explanation: Area of the triangle =+- 15 sq units. =>1/2[X1(y2-Y3)+X2(y3-Y1)+x3(y1-y2)]=+/-15squnits. Put the corresponding value x1,x2,x3 and y1,y2,y3. and solve it. You will get k=21/13 or -3 units.

Answer»

Answer:

The value of K is 21/13units or -3 UNITS.

Step-by-step explanation:

Area of the triangle =+- 15 sq units.

=>1/2[X1(y2-Y3)+X2(y3-Y1)+x3(y1-y2)]=+/-15squnits.

Put the corresponding value x1,x2,x3 and y1,y2,y3. and solve it.

You will get k=21/13 or -3 units.
