1. 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

2. 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

3. 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
