The transformation only needs 5 translations of points to the right. That is what is meant by x+5. Let's take for example the original point P and the transformed point P'. The coordinates of P are (-4,2). Add 5 to -4, the sum would be 1. That's why point P' is at (1,2). The transformed figure is shown in red.
Answer: 
Step-by-step explanation:
See the image attached, where "x" represents the height in feet of the hot air balloon.
Notice that:

To find the lenght of the side BC of the right triangle, you need to use the following Trigonometric Identity:

Observe that:

Substituting values and solving for "BC", you get:

Therefore "x" is:
