Question

Find the area of a triangle whose vertices are (2, - 3), (4, 2) and (7, 6) respectively

Answer 1

Answer:

To find the area of a triangle where you know the x and y coordinates of the three vertices, you'll need to use the coordinate geometry formula: area = the absolute value of Ax(By - Cy) + Bx(Cy - Ay) + Cx(Ay - By) divided by 2..

I hope it's help you..

Answer 2

Answer:

x= 3y + 4z - 5

therefore

y - 1 = z

sin(x-y)= sinxcosy- cosxsiny
