Answer:

C) 5.4 and 5.4

Step-by-step explanation:

CD: 5²+2²=c² = 25+4=c² = 29=c² = c=√29 = 5.4

AB: 5²+2²=c² = 25+4=c² = 29=c² = c=√29 = 5.4

The figure shows two parallel lines AB and DE cut by the transversals AE and BD: AB and DE are parallel lines and AE and BD are
Alik [6]

Answer: Triangle ABC is similar to triangle EDC because Measure of angle 3 equals measure of angle 4 and Measure of angle 1 equals measure of angle 5

Step-by-step explanation:

Given: AB \parallel DE,  AE\cap BD = C

Where AE and BD are the common transversals of parallel lines AB and DE,

Also, Angle CAB is labeled 1, angle ABC is labeled 2, angle ACB is labeled 3, angle DCE is labeled 4, angle CDE is labeled 6, and angle CED is labeled 5.

Thus,   \angle 3 \cong \angle 4   ( Vertically opposite angles )

\angle 1 \cong \angle 5            ( Alternative interior angle theorem)

Thus, By AA similarity postulate,

\triangle ABC \sim \triangle EDC

Hence, proved.

Second Option is correct.
