grin007 [14]

Given:

A rope tied from a tent pole to a stake in the ground forms 55 degrees angle with the ground.

The pole is 3 feet from the stake.

To find:

The length of the rope to the nearest tenth of a foot.

Solution:

First draw a diagram according to the given information as shown below.

We know that, in a right angled triangle,

\cos \theta = \dfrac{Base}{Hypotenuse}

In triangle ABC,

\cos 55^\circ=\dfrac{BC}{AC}

0.573576=\dfrac{3}{AC}

AC=\dfrac{3}{0.573576}

AC=5.23034

AC\approx 5.2

Therefore, the length of the rope is 5.2 foot.
