Answer:
x = 12.17
Step-by-step explanation:
we use the tan function

Multiplicative identity, which states that anything multiplied by 1 is itself.
Answer: SECOND OPTION.
Step-by-step explanation:
For this exercise it is important to remember "Rigid transformations".
Rigid transformations are those transformation that preserves length. These are the following:
- Reflection.
- Tanslation.
- Rotation.
According to the information given in the exercise, the triangle JKL was translated 12 units vertically and then reflected over the y-axis to create triangle J'K'L'. Therefore, JKL and J'K'L' are congruent.
Knowing the above, you can set up the following equation:

The final step is to solve for "x" in order to find its value. You get that this is:

X-y = -10 (the difference of these same numers is -10)
x+y = 6 (the sum of two numbers is 6)
x = 6-y
6-y-y= -10
-2y = -16
y = 8
x = -2
