Answer:
Length of the base of aluminum triangle is 24 inch
Height of aluminum triangle is 10 inch
Step-by-step explanation:
Let's assume height of triangle is h
we are given
The base of the triangle is 4 inches more then twice the height
so, we get length of the base of triangle
now, we can find area of triangle
now, we can plug b
now, we are given that area =120inch^2
so, we can set it
now, we can solve for h
we can factor out 2
now, we can factor it
we can set each terms =0
and then we can solve for h
we know that height can never be negative
so, we will only consider h=10
now, we can find b
Length of the base of aluminum triangle is 24 inch
Height of aluminum triangle is 10 inch
