Theo and Kaci are standing 5 kilometers away from each other, watching a balloon ascending directly between them. The angle of elevation from Kaci to the balloon is 30∘. The angle of elevation from Theo to the balloon is 60∘. How high is the balloon?

#12 the answer is the third option

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.
