Answer:
2 1/2 feet
Step-by-step explanation:
The Pythagorean theorem is not useful in this problem.
__
If you reflect the triangle over the vertical line, you find that line to be the altitude of an equilateral triangle. That is, all of the vertex angles are 60°.
The base of that equilateral triangle is necessarily twice the length of the base of the triangle shown. All sides of the equilateral triangle are the same length, so all are 5 ft. The base of the triangle shown is half that.
The base (short leg) of the triangle shown is 2 1/2 feet.
_____
Since angles are given, this can be solved using trigonometry. The short leg will be (5 ft)·cos(60°) = (5 ft)(0.5) = 2.5 ft. (The cosine of 60° is one of the few exact rational values of trig functions of exact angles measured in degrees.)
The answer is $3.01. To get this answer, divide 18.06 by 6. This is the unit price. 18.6/6. I hope this helps and I hope you have a blessed day.
Answer:
$1,272
Step-by-step explanation:
Just add 1,200 (how much she borrowed) and 6/100*1200 (6 percent of 1200) and you will get the answer of $1,272
