Question

There is a ladder leaning against a wall
6 feet away as shown below. Find the
length of the ladder.
[?]ft
600
6ft

Answer 1

Answer:

12ft

Step-by-step explanation:

use sin cos tan method

here, we can see 6ft as adj to the angle and the ladder as hypotenuse

so, adj/hyp = cosθ

--> 6/hyp = cos60

--> hyp = 6/cos60

--> hyp, length of ladder =  12ft

Answer 2

The length of the ladder is 12ft.

How to find the length of the ladder?

Sine, Cosine, and Tangent are the main functions used in Trigonometry and are based on a Right-Angled Triangle.

Use the sin cos tan method:

Here, we can see 6ft as adj to the angle and the ladder as the hypotenuse

so,  

⇒ adj/hyp = cosθ

⇒ 6/hyp = cos60

⇒ hyp = 6/cos60

⇒ hyp, length of ladder =  12ft.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
