I'm confident that something is missing in the problem you posted unless it is a right triangle which it doesn't appear to be.

hero · Answer

Are you sure that's correct as written?

anonymous · Answer

yes i even looked it over again

anonymous · Answer

im so lost on all of this math stuff

hero · Answer

If it is correct as shown, then you should be able to use the formula for area of a triangle to solve:

$$\text{Area}_{\triangle} = \frac{bh}{2}$$Inputting the proper values, you get:
$$180 = \frac{(4x-16)(2x)}{2}$$

hero · Answer

Now all you have to do is just solve for x properly.
