To support a tree damaged in a storm, a 12-foot wire is secured from the ground to the tree at a point 10 feet off the ground. the tree meets the ground at a right angle. at approximately what angle does the wire meet the ground?
a) 33.6°
b) 39.8°
c) 50.2°
d) 56.4°

The angle is 56.44º

Step-by-step explanation:

We propose the exercise in terms of the rectangular triangle that forms between the tree, the ground and the wire because the exercise propose that the tree meets the ground at a right angle. For this we can see the attached figure.

We need to find the angle between the cable and the ground, and in the figure it is β , if we have the length of the cable and the height of the tree we can say that :

Then β is:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
