Is there a rigid transformation that would map δabc to δdec

Both ΔABC and ΔDEC are congruent, therefore there a rigid transformation that would map ΔABC to ΔDEC.

Step-by-step explanation:

In rigid transformation the size and shape of the figure remain s the same if the original figure and transformed figure are congruent.

In ΔABC and ΔDEC,

                       (Given)

                       (Given)

                       (Given)

By AAS postulate of congruent triangle,

Since both ΔABC and ΔDEC are congruent, therefore there a rigid transformation that would map ΔABC to ΔDEC.

The diagram shows the 180 degree rotation about the point C and the rotation is a rigid transformation.

answer: a

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
