Step-by-step explanation:

Answer:
Part 1) Greta's right, the triangle is incorrect.
Part 2) 
Part 3) The height of the tree is
, Trey’s house is not at risk
Step-by-step explanation:
Part 1) we know that
In the right triangle of the figure


Compare

therefore
The triangle is not correct
Because
The side adjacent to the 30 degree angle should be
and the side opposite the 30 degree angle should be 
Part 2)
Let
x--------> the distance from the airplane to the SCCA (hypotenuse of the right triangle)
we know that



Part 3)
Let
x--------> the height of the tree
we know that



therefore
Trey’s house is not at risk
3n - 5p + 2n = 10p
Since we are solving for n, you want to have all the terms containing the variable n on the left side of the equation and everything else on the right side.
Let's do this by adding 5p to both sides.
3n + 2n = 10p + 5p
Now combine like terms.
5n = 15p
Divide both sides by 5 since we are solving for the variable n.
n = 3p
