7.6 inchesStep-by-step explanation:The area of a triangle can be found using:a=(b*h)/2We 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)/2Now we have to solve for h, by getting h by itself.First, get rid of the denominator of 2 by multiplying both sides by 276*2=20*h/2*276*2=20*h152=20*hNext, divide both sides by 20, because 20 and h are being multiplied.152/20=20*h/20152/20=h7.6=hThe height is 7.6 inchesReply

7.6 = hStep-by-step explanation:The area of a triangle is given byA = 1/2 bh where b is the base and h is the height76 = 1/2 *20 *h76 = 10 hDivide each side by 1076/10 = 10h/107.6 = hReply
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

step-by-step explanation:
1+2+3+4+5+6+7+8+9+10 = 55
2*10 = 20
55-20 = 35
7.6 = h
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh where b is the base and h is the height
76 = 1/2 *20 *h
76 = 10 h
Divide each side by 10
76/10 = 10h/10
7.6 = h
