#

@split rain

#

Hope that helps

#

if u don't get how I got the height and width of the triangle I'll be happy to explain. I see now that, that part wasn't very clear as to how I got it

split rain
#

I get how you found all the points A, B and C but idk how you put it into a triangle like that ??

winter torrent
#

its because the question says find the area of the triangle ABC so after finding the points all I did was connect them

#

and since lines L and M are perpendicular angle ACB is 90 degrees

#

So we can form that triangle

split rain
#

Did you draw the lines L and M too

winter torrent
#

no I didn't draw them on the graph

#

you don't rlly have to but if you want them for visual interpretation you can

#

ALso line AC is apart of line M and line BC is apart of line L
