Answer:
The angle between the ramp & ground is = 68.67 °
Step-by-step explanation:
AC = length of the ramp = 11 ft
BC = 4 ft
From the ΔABC
[tex]\cos \theta = \frac{BC}{AC}[/tex]
[tex]\cos \theta = \frac{4}{11}[/tex]
[tex]\theta =[/tex] 68.67 °
Therefore the angle between the ramp & ground is = 68.67 °
