Answer:
c=-9x^2-15x
Step-by-step explanation:
Answer:
768
Step-by-step explanation:
because 50 percent of the num is 96 you double that and then multiply by four
I believe it's 12 because 5*16=80. So, then you would subtract 4 from 16 and gat 12.
Answer:
The distance from point A to the top of the building is 5
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
