Question

Order the side lengths DE, EF, and FD from least to greatest. (Note that the figure is not drawn to scale.) F 74 61° E D x°

Answer 1

1) Given the angles of the following figure, we can write:

2) Since the size of each leg is directly proportional to the measure of the angle, i.e. the wider the angle the bigger the opposite leg, we can write the order from least to greatest:

FE, DF and DE

or

FE < DF < DE
