Problema Solution
the area of a triangle is represented by (20+x). if the hieght is 8 inches and the length is represented by (4x+20). what is the length of the base.
Answer provided by our tutors
let
h = 8 in the height of the triangle
b = 4x + 20 in the base of the triangle
A = 20 + x in^2 the area of the triangle
are of a triangle = (base * heights)/2
A = (b*h)/2
20 + x = 8*(4x + 20)/2
20 + x = 16x + 80
x = -15
b = 4(-4) + 20 = 4 in
the length of the base is 4 in.
