Question 189382: If the area of a triangle is 40 cm^2 and the base equals (2h + 6), what is the height?

Here is what I tried.
A=1/2bh
40=1/2(2h + 6)(h)
40= (h^2 + 3h)(h)
40= h^3 + 3h^2
stuck here. Thanks for the help

Question 186113: Hi. I have a problem that I'm having difficulty solving, and I'm curious if I have even been given enough information.

Without the ability to draw, this may get a bit hairy to describe, so I do apologize.

I have a triangle ABD, and there is a line segment BC which cuts the original triangle into 2 triangles (C is a point on the line segment AD).

We are given the following:
Angle ADB is 90 degrees.
Length of BD is
Length of AC is

We are supposed to find the angle ABC.

I can't figure out how to do this problem, as it doesn't seem like enough information has been given. If you could please either confirm this or explain to me how to go about doing this problem, I would greatly appreciate it. Thank you.
