The answer is 4.8873, so you can say over 4 times as great, or almost 5 times as great for the first question.

And I think the second question could be because those over 35 years old have a more stable career, they're more developed skill-wise & worth more to their company so they're paid more, and of higher ranking in their professions, etc.

A 22-ft ladder leans against a building so that the angle between the ground and the ladder is 64°. How high does the ladder rea

vodka [1.7K]

The height of the ladder on the building is 19.77 feet

<h3>How high does the ladder reach on the building?</h3>

Represent the height of the ladder on the building with h

So, the given parameters are:

Angle, x = 64 degrees

Length of ladder, l = 22 feet

The height of the ladder on the building is calculated using

sin(x) = h/l

Substitute the known values in the above equation

sin(64) = h/22

Multiply both sides by 22

h = 22 * sin(64)

Evaluate the product

h = 19.77

Hence, the height of the ladder on the building is 19.77 feet
