Question: the length of one side of a triangle is 2cm less than twice the length of the altitude to that side. the area of the triangle is 30 cm squared. find the length of the altitude.
first of all, what is an altitude? and how do i find it?

 


Colby,

I let the length of the side be x and the height be h hence the area is 1/2 x h = 30.

But x = 2h - 2.
