Answer:
Step-by-step explanation:
3a + 2 = -2n + 3p 
3a = -2n + 3p - 2
a = (-2n+3p-2)/3
a = -2/3(n) + p - 2/3

Answer:
The distance from point A to the top of the building is 5 feet
 feet
The Height of the Skyscraper is 5 feet
Step-by-step explanation:
Given 
Let Top point of building be point C
Also Let Base of the building be point  B
Distance from point A to base B of the building AB= 5 feet
∴ It makes a Right angle triangle
Also ∠ACB = 45°
Also tan 45° = 1
Now tan ∠ACB =
∴ AB= BC =5 feet
The Height of the Skyscraper is 5 feet
Now Triangle ABC is right angle triangle with right angled at B
So by Pythagoras theorem
AC= 
The distance from point A to the top of the building is 5 feet
 feet
