Answer:
C
Step-by-step explanation:
If we were to draw a horizontal line from the bottom of the ladder to the bottom of the tree and then draw a vertical line from the bottom of the tree to the top of the ladder, we'd get a right triangle with legs as the distance between the bottom of the tree and the bottom of the ladder and the height of the ladder, and the hypotenuse is the length.
Here, we know the hypotenuse is 10 feet and that the bottom of the ladder is 4 feet away from the bottom of the tree, so use the Pythagorean Theorem to find the height:
h =
≈ 9.2 feet
The answer is C.
Answer:
Step-by-step explanation:
25 km / 100 km/hr = 0.25 hr or 15 minutes
Answer:
9.5
Step-by-step explanation:
The legs of the triangle are
3 and 9
From the Pythagorean Theorem
c² = a²+ b²
c² = 3² + 9²
c² = = 9 + 81
c² = 90
Take the square root of both sides
c = 9.4868329805
Rounded
9.5
