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.

AleksandrR [38]

The length of the pieces originally were 1/4 yards.

Jamie then cuts them into a 1/3 of their original length.

The new length is therefore:

= Original length * proportion of original length strips are cut into

= 1/4 * 1/3

= 1/12 yards
