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.
<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:
The line of best fit is used to express a relationship in a scatter plot of different data points.
Step-by-step explanation:
Y=MX just substitute each X value into the equation for example Y= 3 x 2 (3 x 2 is 6 so Y would be 6) I hope this helps somewhat! ^^;
x-coordinates for the maximum points in any function f(x) by f'(x) =0 would be x = π/2 and x= 3π/2.
<h3>How to obtain the maximum value of a function?</h3>
To find the maximum of a continuous and twice differentiable function f(x), we can firstly differentiate it with respect to x and equating it to 0 will give us critical points.
we want to find x-coordinates for the maximum points in any function f(x) by f'(x) =0
Given f(x)= 4cos(2x -π)
In general
from x = 0 to x = 2π :
when k =0 then x = π/2
when k =1 then x= π
when k =2 then x= 3π/2
when k =3 then x=2π
Thus, X-coordinates of maximum points are x = π/2 and x= 3π/2
