Answer:
6
Step-by-step explanation:
Area of triangle equation:
A=[tex]\frac{1}{2}[/tex] base * height
For this triangle...
12=[tex]\frac{1}{2}[/tex] (4) (x)
we need to figure out what x is to find the height.
To get x alone in this equation we can first divide both sides by 4
12/4=[tex]\frac{1}{2}[/tex] (x) ---> 3= [tex]\frac{1}{2}[/tex] (x) Then multiply by the reciprocal of 1/2 which is 2/1
x=6
