Question

what is the value of x.
A. 17
B. 16
C. 16.5
D. 15

Answer 1

Answer:

Step-by-step explanation:

Because angle FGH and angle HGE are congruent, that angle bisector, namely GH, separates this largr triangle into one that shares sides in proportion to each other.  

That means that $\frac{x}{13.5} =\frac{68}{54}$

Cross multiply to get

54x = 918 and

x = 17
