The base of a triangle is 9 inches more than 3 times the height. if the area of the triangle is 105 square inches, find the base
wolverine [178]
So to solve you need to set up equations, Using h as the height. So the base is 9 inches more  (+9)  than 3 times the height (3h) so 3h+9 equals the base. You have the area so you need to plug in the equation for the base and h for height and divide it all by 2. h(3h+9)/2=105. after you solve that and get h by itself you should get h= 7 and the b= 30

I do 10 - 8 for this, right...?
natima [27]
No, you would do 100 - 64 because 10^2 is 100 and 8^2 is 64.
100-64= 36
The square root of 36 is 6. The length of the other leg is 6.
