Question

How far up a wall will an 11-meter ladder reach, if the foot of the ladder is 4 meters away from the base of the wall? A. 11m B. 4m C. sq rt of 105m D. sq rt of 245m

Answer 1

C. √105m

Explanation:

From the case, it will make a triangle with a 4m base and 11m slope.

To find the height, we can use the Pythagorean theorem.

slope² = base² + height²

11² = 4² + y²

121 = 16 + y²

y² = 121 - 16 = 105

y = √105

So, the answer is (C) √105m
