Question

A fireman learned a 36 foot ladder against a building.If he placed the ladder 7 feet from the base of the building,what angle is formed between the ladder and the ground?​

Answer 1

Answer:
The angle between the ladder and ground is 78.78°

Step-by-step explanation:
It is given that the length of the ladder is 36 foot and the distance between the base and the ladder is 7 feet.

Here we can see that the hypotenuse is 36 foot and the base is 7 feet. To find the angle between the ladder and the ground we take the cos inverse of 7/36.

Let the angle between the ladder and the ground is ‘x’.
