    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

    marco saved more.   he saved $35 more.

    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
