An expression for the base of the triangle: Response area
Equation for the area of the triangle, substituting in for the base: Response area
The first step in solving for h:
An expression for the base of the triangle: 3h - 4
Equation for the area of the triangle, substituting in for the base: 38 = (3h - 4 * h) / 2
The first step in solving for h: Multiply both sides of the equation by 2.
The first step in solving for h is to rearrange the equation of the area of the triangle and substitute the expression for the base.
So the equation for the area of the triangle, substituting in for the base, is:
A = (b * h) / 2
Now, let's substitute the expression for the base:
A = ((3h - 4) * h) / 2
Now we can simplify the equation and continue solving for h.
