Textbook Problem

In Exercises 5 to 22, find the missing lengths. Give your answers in both simplest radical form and as approximations correct two decimal places.

Given: Right D E F with m F = 30 ° and F E = 12
Find: D F and D E

To determine

To find:

DF and DE of the right DEF with mF=30° and EF=12.

Explanation

Approach:

For a right triangle, for which the measure of the interior angles 30°, 60°, and 90°; if ‘a’ is the length of measure of the shorter leg; opposite to the angle 30°, then the length of the other two sides is given by

Length of the longer leg (opposite to 60°) =a3

Length of the hypotenuse (opposite to 90°) =2a.

In general

Length of the longer leg =3× (Length of the shorter leg)

Length of the hypotenuse =2× (Length of the shorter leg)

Calculation:

Given,

A right triangle DEF with mF=30° and EF=12.

Since, one of the acute angle mF of the right triangle is 30°, then the other acute angle mE should be 60°.

Thus, the XYZ is of the type 30°-60°-90° triangle.

30°-60°-90° theorem.

In a right triangle whose angle measure 30°, 60°, and 90°, the hypotenuse has a length equal to twice the length of the shorter leg, and the longer leg is the product of 3 and the length of the shorter leg.

For the given triangle EF=12, and mF=30° and mE=60°
