Given: dc||ab dc = ab

based on the given information and the algebraic and geometric properties presented or proven thus far, choose the congruence theorem that could be used to prove the triangles congruent. if it is not possible to prove the triangles are congruent, choose "not possible".

Step-by-step explanation:

Given,

DC || AB,

DC = AB

We have to prove that : triangles shown in the diagram are congruent.

Proof :

Since, in triangles ADC and ABC,

AC ≅ AC ( common segments ),

DC || AB

⇒ ∠DAC ≅ ∠ ACB  ( By alternate interior angle theorem )

DC = AB  ( given )

Hence, By SAS ( side - angle - side ) postulate of congruence,

Δ ADC ≅ Δ CAB,

Second option is correct.

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.

step-by-step explanation:

the answer is 0.071
