Answer:
The answer to your question is 13.2 ft
Step-by-step explanation:
Data
length of the ladder = hypotenuse = 16 ft
adjacent side = 9 ft
opposite side = ?
Process
1.- To solve this problem use the Pythagorean theorem
c² = a² + b²
Solve for b²
b² = c² - a²
2.- Substitution
b² = 16² - 9²
3.- Simplification
b² = 256 - 81
b² = 175
b = 13.2 ft
4.- Conclusion
The ladder is 13.2 ft resting against the building.
Answer:
a=-27
Step-by-step explanation:
⅓a-6=-15
multiply by 3 on both sides
3(⅓a-6)=3(-15)
a-18=-45
add 18 on both sides
a=-45+18
a=-27
The circle would have a center at the origin. The radius is 6, the area is 36pi and the perimeter is 12pi. I have attached an image of the circle below.
