Use the Pythagorean theorem:
70^2 = 42^2 + width^2
4900 = 1764 + width ^2
Subtract 1764 from both sides
3136 = width^2
Take the square root of both sides
Width = 56 inches
Answer:
13 feet long
Step-by-step explanation:
This situation forms a right triangle, where the ladder is the hypotenuse, the distance away from the building is the short leg, and the height to the side of the building is the long leg.
Use the pythagorean theorem, and solve for c, the hypotenuse:
a² + b² = c²
5² + 12² = c²
25 + 144 = c²
169 = c²
13 = c
So, the ladder is 13 feet long
The answer is 40..........
Answer:
The answer for 10 is y= -4x+2
If the slope is exactly the same but the y intercept is different then it will be parallel
The answer for 11 is y-5=-3/2 (x-1)
