Question

H, W and T are collinear points on a line segment. If HT = 57 and WT = 22, find the length of [line segment] HW

Answer 1

Lets try to draw a basic diagram:

From the diagram, we can simply see that:

HW + WT = HT

Given HT = 57 and WT = 22, so we have:

HW + WT = HT

HW + 22 = 57

Thus, solving for HW gives us:

HW = 57 - 22

HW = 35
