The formula for the area of a triangle is:

Take the information you have in the problem, and substitute.
A = 54
b = 12

So, the problem looks like this:

Simplify the right hand side of the equation by multiplying 1/2 and 12.

Then divide both sides by 6, since division is the opposite of multiplication.

So, the height is 9 inches.

let one angle=x
2nd angle =x+58
x+x+58=180
2x+58=180
x=16
x+58=y
