triangle abc is translated by the rule (x + 1, y + 1) and then dilated by a scale factor of 2 centered at the origin. which statement describes the properties of triangles abc and a''b''c'' after the transformations?

a. ∠c and ∠c'' are congruent after both the translation and the dilation.

b. ∠c and ∠c'' are congruent after the dilation, but not after the translation.

c. segment ac and segment a double prime c double prime are congruent after both the translation and the dilation.

d. segment ac and segment a double prime c double prime are congruent after the dilation, but not after the translation.

Option A. ∠C and ∠C'' are congruent after both the translation and the dilation

Step-by-step explanation:

we know that

The translation is a rigid transformation. After the translation the image and the pre-image are congruent

The dilation is a non rigid transformation. After the dilation the image and the pre-image are similar

Remember that

If two figures are similar, then its corresponding angles are congruent and the ratio of its corresponding sides is proportional

If two figures are congruent, then its corresponding angles and corresponding sides are congruent

therefore

∠C and ∠C'' are congruent after both the translation and the dilation

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
