Item 10 A 12-foot ladder leans against the side of a house with its base 3 feet from the house. Use the Pythagorean Theorem to a
pproximate how high the ladder reaches up the side of the house. Round your answer to the nearest hundredth
1 answer:
Answer:
11.6 foot
Step-by-step explanation:
Length of the Ladder=12 foot
Distance of the base of the Ladder from the House=3 foot
Since the ladder leans against the wall in a slant position, it is the hypotenuse.
From Pythagoras Theorem,
Hypotenuse ²= Opposite ²+ Adjacent ²
12²=3²+x²
x²= 12²-3²=144-9=135
x=√135=11.61895003862
The Ladder reaches up to a height of 11.6 foot (to the nearest tenth) on the house.

The answer is 4+5+6=15.Hope that helps. :)
Step 1:
Set Variables (We will use x & y)
x = years
y = total orangutan population
Step 2:
Set up Equations
784 - 25x = y
817 - 36x = y
Step 3:
Set equations equal to each other & solve
784 - 25x = 817 - 36x
784 = 817 - 11x
-33 = -11x
3 years = x
