Answer please struggling

Julli [10]

Answer:

x ≈ 28.2

Step-by-step explanation:

Δ CAB ≅ Δ CDE then corresponding sides are in proportion, that is

$\frac{CA}{CD}$ = $\frac{CB}{CE}$ , substitute values

$\frac{14+x}{x}$ = $\frac{18.7+9.3}{18.7}$ = $\frac{28}{18.7}$ ( cross- multiply )

28x = 18.7(14 + x) ← distribute

28x = 261.8 + 18.7x ( subtract 18.7x from both sides )

9.3x = 261.8 ( divide both sides by 9.3 )

x ≈ 28.2 (to the nearest tenth )

Question 12 (5 points)

NemiM [27]

Answer:

D) If WX = XY and XY = YZ, then WX = YZ.

Step-by-step explanation:

The transitive property states that if a=b and b=c, then a=c. So, if two different values equal to the same, separate value, then they are also congruent. The answer choice, d, represents this idea because WX and YZ both equal XY and are shown to be equal.
