Answer 2

Given :

The angle made by ramp with the ground = 15°

The distance of ramp end from base of building = x = 10 feet

To Find :

The measure of length of ramp

Solution :

Let the measure of length of ramp = y feet

From figure

Cos angle = $\dfrac{Base}{Hypotenuse}$

Or,  Cos 15° = $\dfrac{x feet}{y feet}$

Or,  0.9659 = $\dfrac{10 feet}{y feet}$

∴       y = $\dfrac{10 feet}{0.9659}$

i.e     y = 10.35  feet

Or, Length = y = 10.35 feet

Hence, The measure of length of ramp is 10.35 feet  Answer
