A 12-m ladder is leaning against a wall.

Len [333]

Answer:

Step-by-step explanation:

Use Pythagorean's Theorem for a right triangle. Your best bet when learning/visualizing word problems is to draw a picture, then learn how to visualize in your head over time.

$3^2+x^2=12^2\\9+x^2=144\\x=\sqrt{135}$

The radical can be further simplified because 135 is the product of 9 and 15. 9 has a perfect root of 3.

$x=3\sqrt{15}$ meters or 11.62 meters
