<h3>What is trigonometry?</h3>
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
From the right-angle triangle:
Let's suppose the height of the portion AB is x ft
We know cos is the ratio of the adjacent to the hypotenuse.
From the figure:
ft
Thus, the height of the portion AB is 10 divided by cos 50 degrees if the CAB, is bent at point A after a storm. The tip of the lamppost touched the ground at point C.

Answer:3y-3y=0
Step-by-step explanation: They are giving you a value for X that is 3y. You put that value in place of x. So, if x=12 and they want you to substitute for x-3y=0, you would have 12-3y=0....but the value of x in your question is 3y....so you replace the x in the equation with it's value...which is given to you as 3y....or in my example, 12.
