The area of triangle ABC is 494in^2. Find the height if AC = 19 inches.

recall that area of triangle is just

A = (1/2)(bh)
where
b = base
h = height
since we need to find the height, thus the given AC is the base. substituting,
494 = (1/2)(19)*h
988 = 19*h
h = 988/19
h = 52 inches

hope this helps~ :)
