<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:
10x² + 3xy + 3x - y² + 3y
Step-by-step explanation:
(2x + y)(5x - y + 3)
10x² - 2xy + 6x + 5xy -y² + 3y
10x² + 3xy + 3x - y² + 3y
Answer: x = -5
Step-by-step explanation:
-3.4x - 9 = 8
+9 +9
-3.4x = 17
-3.4x ÷ -3.4 = x
17 ÷ -3.4 = <u><em>-5</em></u>
