What is the value of x to the nearest tenth? The diagram is not drawn to scale. Picture attached. Thank you.
sveta [45]

Answer: 14.4

===================================

Work Shown:

Use the angle bisector theorem to divide each side adjacent to the congruent angles (x and 13.5) over their corresponding sides that are adjacent to those previously mentioned sides.

So in short we have x/6.6 as one ratio, and 13.5/6.2 as another

Equate the two fractions, cross multiply, solve for x.

x/6.6 = 13.5/6.2

x*6.2 = 6.6*13.5 ... cross multiply

6.2x = 89.1

6.2x/6.2 = 89.1/6.2  .... divide both sides by 6.2

x = 14.371 which is approximate

x = 14.4
