The base of the ramp is 12.96 feet long.
The cos angle is defined as the ratio of hypotenuse height or base.
[tex]\rm Cos\theta=\dfrac{Base}{Hypotenuse}[/tex]
Given
The ramp rises are 14 feet long high and rise at an angle of 22.2 degrees.
Then,
The length of the base is given by;
[tex]\rm Cos\theta=\dfrac{Base}{Hypotenuse}\\\\\rm Cos22.2=\dfrac{Base}{14\\}\\\\Base= Cos22.2 \times 14\\\\Base=14 \times 0.92\\\\Base=12.96[/tex]
Hence, the base of the ramp is 12.96 feet long.
