Answer:
7.6 inches
Step-by-step explanation:
The area of a triangle can be found using:
a=(b*h)/2
We know that the area is 76 in^2 and the base is 20 in. Substitute 76 in for a and 20 in for b.
76=(20*h)/2
Now we have to solve for h, by getting h by itself.
First, get rid of the denominator of 2 by multiplying both sides by 2
76*2=20*h/2*2
76*2=20*h
152=20*h
Next, divide both sides by 20, because 20 and h are being multiplied.
152/20=20*h/20
152/20=h
7.6=h
The height is 7.6 inches
