Now to find the height x, notice how the smaller triangle is similar to the larger one. So this means that the corresponding sides form the same ratio. So this means that {{{x/176=112/64}}} (ie the ratio of the height to the horizontal distance is the same). Simply solve {{{x/176=112/64}}} to find the height 'x'.
