Completed Question

1. OSHA is an agency responsible for workplace safety, read its rule and sketch a  diagram that shows the proper relationship between the ladder, wall and ground .

Rule: Non-self-supporting ladders, which must lean against a wall or other support, are to be positioned at such an angle  that the horizontal distance from the top support to the foot of the ladder is about the 1/4 working length of the ladder.

2. Calculate the angle that the ladder makes with the ground using a trigonometric ratio.

3. If a ladder is x feet long, how high up a wall can it safely reach?

4. Would a 51-foot ladder be long enough to climb a 50-foot wall?

(a)See attachment

(b)75.52 degrees

(c)

(d) NO

Step-by-step explanation:

Part 1

Let the length of the ladder =x

Since by the given rule, Horizontal Distance =

Horizontal Distance =

In the sketch of the problem attached below,

Part 2

From Triangle ABC

The angle that the ladder makes with the ground is 75.52 degrees.

Part 3

If the ladder is x feet long

Using Pythagoras theorem in Triangle ABC below

Part 4

If x=51 feet

Therefore, a 51 feet ladder would not be enough to climb a 50 feet wall as it would violate the safety rule.
