Question

A 15 foot ladder side of the building if the base of the ladder is 6 feet from the bottom of the wall which expression can be used to find the angle formed by the latter and the ground.

Answer 1

Answer: the answer is c

Explanation:

Answer 2

The angle formed by ladder and the ground is
`66.42^\circ`.

Explanation:

Given that, a 15 foot ladder lent against to the side of the building. 6 feet is the distance from the bottom of the ladder to the wall.

It looks like a right angled triangle whose hypotenuse 15 foot and base 6 feet.

We know that,

`cos\theta=(Base)/(Hypotenuse)`

`\Rightarrow cos\theta = (6)/(15)`

`\Rightarrow cos\theta = (2)/(5)`

`\Rightarrow \theta = cos^ {-1}((2)/(5))`

`\Rightarrow \theta =66.42^\circ`

The angle formed by ladder and the ground is
`66.42^\circ`.
