<u>Answer:</u>
The correct answer option is B. 21.
<u>Step-by-step explanation:</u>
We are given a figure where the line KL is intersecting another line MN such that angle from K to N is equal to the angle opposing it which is the angle measuring .
Measure of angle K - N = 90° + 15° = 105°
Since angle K - N = angle M - L, we can write it as:
105° = 5x
x = 105/5
x = 21
Therefore, the correct answer option is B. 21.
We need to simplify this number. We begin by evaluating the numbers inside the equation. We can simplify this to:
Now, we evaluate this one step further. Because a negative exponent makes the number 1 over what it was, we can make this problem:
This becomes:
So, 1/4k is the answer. This is the same as C, so C is the right answer.
