Answer:
The answer must be D
Step-by-step explanation:
When a shape like a trapezoid is rotated, the figure will remain the same which means that a rotation will not change the measure of the angles, or the measure of the sides, therefore d must be correct because a rotation is a rigid transformation.
Answer:

Step-by-step explanation:
In any "solve for" scenario, you identify what operations are performed on the variable of interest, then undo them in reverse order.
Here, the square root of d is multiplied by a constant. To undo these operations, we first divide by the constant. That gives ...

Then, we square both sides of the equation to undo the square root:

This matches choice C.
