Answer:
Biff's tree is 14 m off the ground and Rocco's tree is 7 m off the ground.
Step-by-step explanation:
Let the height of Biff's tree be represented by x, so that the height of Rocco's tree is  .
.
Draw a straight line from Rocco's point of view to a point t to the middle of Biff's tree. This line divides x into two equal parts, and the angle is divided into  each.
 each.
By alternate angle property, 
Tan   =
 = 
 = Tan
 = Tan   × 10
 × 10
   = 7.00021
⇒       x = 2 × 7.0021
             = 14. 0042
          x = 14
Therefore, Biff's tree is 14 m off the ground and Rocco's tree is 7 m off the ground.

Answer:
Step-by-step explanation:
This question isn't worded the greatest, there are two ways you can read this.
1.  The quotient of a number and -9, increased by 10, is 11
2. The quotient of a number, and -9 increased by 10, is 11
The first equation will look like this 

And the second will look like this

So I have solved for both (I personally believe the second way of reading the question is the correct way)
