Answer:
If you know the base and area of the triangle, you can divide the base by 2, then divide that by the area to find the height. To find the height of an equilateral triangle, use the Pythagorean Theorem, a^2 + b^2 = c^2.
For this , you use the distance formula
. based on the graph, use points (0,6) and (7,-2), plug them into the formula to get
![\sqrt{113}](https://tex.z-dn.net/?f=%20%5Csqrt%7B113%7D%20)
and you get B, 10.63
Addition bc. you need adding to both sides x and will get this result of 3x+2 = 11
