What is the GCF for each set of numbers 12 and 20

1 answer:

8 0

4 is the GCF.

Explanation:
4x3=12
4x5=20
5 Isn’t a factor of 12, and 6 isn’t a factor of 20. Each number above doesn’t work, so the greatest common factor of the numbers 12 and 20 must be 4.

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.
