Answer:
The angle between the ramp and the horizontal is 11.54 degrees 
Step-by-step explanation:
Here, we want to get the angle between the ramp and the horizontal 
What we have to do here is to bring the measure of 2 m near to the edge leftwards, so we can have a right triangle 
Now, the angle we want to calculate is the angle that faces the measure 2 m
The given measure of 10 m will represent the hypotenuse of the right triangle 
The trigonometric ratio that links the hypotenuse and the opposite is the sine 
The sine is the ratio of the opposite to the hypotenuse 
Thus, we have it that;
sin theta = opp/hyp
sin theta = 2/10
sin theta = 0.2
theta = sin^-1 0.2
theta = 11.54
