Figure b is a rotation of figure a about point c.

which of the following is true?

a. the two figures are congruent.
b. figure a is a translation.
c. the two figures are similar but not congruent.
d. figure b is a dilation.

A. The two figures are congruent.

Shapes are congruent if you can turn one into the other by moving, rotating or flipping. These two shapes are rectangles. A rectangle is a quadrilateral whose angles are all right angles. So if you take rectangle A, and rotates it 90 degrees, then moving it to match rectangle B, you can realize that these two rectangles are the same shape.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
