Question

A lamppost, CAB, bent at point A after a storm. The tip of the lamppost touched the ground at point C, as shown below:

Answer 1

Answer:

I believe the answer is 10 divided by tan 50 degrees

Step-by-step explanation:

Answer 2

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.

What is trigonometry?

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:

$\rm cos50 = \dfrac{10}{x}$

$\rm x = \dfrac{10}{cos50\°}$ 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.
