10 m
II
5 m
If the ladder is 10 m long and 5 m from the base of the building, how high
up the building will the ladder reach?
(1 point)
○ 5^2 + x²= 10²; x = √75 m, which is an irrational number and would be
estimated to be 8.7 m.
○ 5^2 + x²= 10²; x = 75 m, which is a rational, whole number
○ √10^2 +52 = c²; c = √125, which is an irrational number and must be
estimated at 11.2 m.
○ 102 +52 = c²; c = 125 m, which is a rational, whole number
○ 5^2 + x² = 10²; x = √75 m, which is an irrational number and would be estimated to be 8.7 m.
are u sure
I apologize for the mistake. Let me correct that.
Using the Pythagorean theorem, where the square of the hypotenuse is equal to the sum of the squares of the other two sides:
5^2 + x^2 = 10^2
25 + x^2 = 100
x^2 = 100 - 25
x^2 = 75
x = √75
x ≈ 8.7
So, the ladder will reach approximately 8.7 meters up the building. Thank you for pointing that out.
