To solve this question we will make use of the "Triangle Angle Bisector Theorem", which states that, "An angle bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle."
Thus, in our question, we will have:
The above equation can be rearranged as:
...(Equation 1)
If we have a proper look at the denominator which is , we note that in
,
Thus, (Equation 1) wil give us:
<u>Therefore, LB= 12 feet</u>
<h3>Solving for the measurements of Complementary Angles</h3><h3>Answer:</h3>
and
Recall that Angles that are complementary to each other add up to .
Let be the measure of the complementary angle.
If an angle is more than its complementary angle, the measure of that angle is
. The sum of both angles are expressed
but since the have to add to
as they are complementary,
.
Solving for :
Since the other angle measures , we can plug in the value of
to find the measure of the angle.
Evaluating :
The measure of the angles are and
