Answer:
Step-by-step explanation:
The angles <JKL, <EKL, and <JKE form a full angle which means their sum is equal to 360:
134 + 21x + 6 + 5x = 360 add like terms
140 + 26x = 360 subtract 140 from both sides
26x = 220 divide both sides by 26
x = 8.4 approximately
to find the angle m<JKL replace x with the value we found.
About $5.26 will be deducted from $50
So he will get $44.74
Answer: 
Step-by-step explanation:
The complete exercise is: "The circumference of a circle is 47.1 and the diameter of the circle is 15. Which best represents the value of π? "
In order to solve this exercise, it is important to remember that the circle can be calculated with the following formulas:
1. 
Where "C" is the circumference of the circle and "D" is the diameter of the circle.
2. 
Where "C" is the circumference of the circle and "r" is the radius of the circle (Remeber that the diameter is twice the radius).
In this case, the exercise gives you the circumference of the circle and its diameter. These are:

Then, knowing those values, you can substitute them s into the first equation
, as following:

The final step is to solve for
:
