Question 182192: The question asks to create a graph of the followinf lines y=3/5x-4
y=-1/3x+2 and y=-5x-7 and indicate the points of intersection which i think i did because the next section says you should now have a triangle formed by the intersection of the three lines. Which i have graphed and it does make a triangle now it says to find the area of the triangle using two methods
Method 1 A=1/2 bh
Method 2 heron's formula
the second one is stressing me out my instructor has not taught us this and i'm supposed to figure it out on my own but i just keep getting lost trying to find the area of the triangle.Any help will be greatly appreciated Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! The question asks to create a graph of the followinf lines y=3/5x-4
y=-1/3x+2 and y=-5x-7 and indicate the points of intersection which i think i did because the next section says you should now have a triangle formed by the intersection of the three lines. Which i have graphed and it does make a triangle now it says to find the area of the triangle using two methods
Method 1 A=1/2 bh
Method 2 heron's formula
:
Hero's formula states (where a,b,c are lengths of the 3 sides)
s =
then the area of a triangle is given by:
A =
:
you have to know the lengths of the 3 sides which you can find using
the x/y coordinates of the three intersections and the
the distance formula: d =
;
does this help you?
