ok, so im in algebra 1 and i need help with this problem....im supposed to find teh height of the triangle with a base of 2x and the area is 5

the formula for finding the area is
a=1/2bh  which converts to
5=1/2(2x)(h) which converts to
10=1/2h h therefore is 5 rite?  or maybe 5x rite?  plz help because no one in my family can figure it out!

you can't solve a problem that has 2 variables in it.

you need a different method of solving?

Area = (B * H) / 2

5 * 2 = (2 * X)

Figure the rest out.
