Step-by-step explanation:
The ladder forms a right angle triangle with the building and the ground. The length of the ladder represents the hypotenuse of the right angle triangle. The height, h from the top of the ladder to the base of the house represents the opposite side of the right angle triangle.
The distance from the foot of the ladder to the base of the house represents the adjacent side of the right angle triangle.
To determine the height, h that the ladder reaches, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
15² = 9² + h²
225 = 81 + h²
h² = 225 - 81 = 144
h = √144 = 12 feet
Answer:
4b^-1
Step-by-step explanation:
16a/4 = 4a
4a/a = 4
4/b = 4b^-1
Answer:
The answer is <u>B. Two parallel lines lie in the same plane.</u>
Step-by-step explanation:
- <u>Parallel lines never cut (intersect) or meet each other, and they lie on the same plane. </u>
All the other stuff, east/west, doesn't matter.
He drives 3 miles north, then later on he drives 4 more miles north:
3 + 4 = 7
