Which expression can be used to find the value of x? An upside down scalene triangle A B C. The base side is A B. Side A C is labeled as 9. Side B C is labeled as x. Angle A is labeled as 42 degrees. Angle B is labeled as 29 degrees.

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.

the answer would be  

a.

3: 1

step-by-step explanation:

here the answers ur welcome also plz mark as brainliest if someone else anwers

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
