Answer:
B
Step-by-step explanation:
We should visualize the ramp and the building forming a right-triangle.
Please check attachment for the expected diagrammatic representation.
Now, what we are asked to calculate here is the hypotenuse which represents the length of the ramp.
Whet we have however is the length of the adjacent.
Mathematically, the trigonometric ratio that links the adjacent and the hypotenuse is the cosine
Mathematically Cosine of an angle = length of adjacent/length of hypotenuse
looking at the diagram, our angle is 7 while our adjacent is 6 feet
Using change of formula subject;
Cos 7 = 6/hypotenuse
hypotenuse = 6/Cos 7 = 6.05 feet
