a. draw a sketch of the triangle
b. draw the altitude from vertex A
c. find the slope of side BC which is =-1/4
d. find the slope of the altitude from A which is 4
e. find the equation of the line that contains this altitude which y=4x-8
f. find the length of this altitude
g. find the area of the triangle.
i know from A-E BUT i do not know F and G. I have been trying my best but i did not get it can you help me pls. it is very urgent. thanks.
