Answer: Height is 5 units.
Step-by-step explanation:
Alright, lets get started.
The area of the triangle is [tex]A=\frac{1}{2} \times b \times h[/tex]
The area is given as 30
The base is given as 12
Plugging the values in formula
[tex]30=\frac{1}{2} \times 12\times h[/tex]
[tex]30=6\times h[/tex]
Dividing 6 in both sides
[tex]\frac{30}{6}=\frac{6\times h}{6}[/tex]
[tex]5=h[/tex]
[tex]h=5[/tex]
Hence the height of the triangle is 5 units.........Answer
