<span> Pythagorean right triangle
a^2 + b^2 = c^2
Let the length of the ladder be x.
One side is x - 16.
The other side is x - 8.
</span><span>(x-16)^2 + (x-8)^2 = x^2
</span>
x^2 - 32x + 256 + <span>x^2- 16 x+64 = x^2
x^2 - 48 x + 320 = 0
( x- 40 ) (x-8) = 0
x = 40 or x= 8
we discard the second so x = 40

Answer:
Distance = Square Root ((X2 - X1)^2 + (Y2 - Y1)^2)
Distance = Square Root ((7 -13))^2 + ((10 -2))^2
Distance = Square Root ((-6))^2 + ((8^))2
Distance = Square Root (36 + 64)
Distance = 10
Step-by-step explanation:
Answer:
5 feet
Step-by-step explanation:
When you place a 13-food ladder against the top of a 12-foot building, the ladder becomes the hypotenuse of the right angle triangle formed.
Let x be the distance of the bottom of the ladder away from the bottom of the building.
Using the Pythagoras Theorem we obtain:
This implies that:
The bottom of the ladder will be 5 feet away from the bottom of the ladder
Answer:
C) 1/8 inch
Step-by-step explanation:
We are given the explicit formula
, where n is the term number.
The third climb up would be the third term; this means we replace n with 3:
We have an equation: ?/100= 25/752
Cross multiply:
752*?= 25*100
⇒ ?= 25*100/752= 3.32
3.32% of 752 is 25~
