To prove : VBYZ is a parallelogram.

Explanation of Solution
Given information : The following information has been given
Formula used : Information/data provided in the question that are used to solve this particular category of solution/solution.
Proof : We know that
Thus, we can say that ZV and YB are parallel lines
Now, we use
Thus, triangles AZV and XBY are similar triangles
Now, we know that as ZV and YB are parallel lines with all similar angles,
Hence, opposite lines are parallel and equal − thus, VBYZ has to be a parallelogram

Mariela’s line of sight to the top of the tree creates a 42° angle of elevation, and her line of sight to the base of the tree creates a 31° angle of depression. What is the height of the tree, rounded to the nearest foot? Be sure to show your work to explain how you got your answer.arrow_forward
