You're not gonna like it. I think both I and III are true, so none of the choices shown. Choice E: I and III.

I. H and J are points, and any two points are on some line, so collinear. TRUE.

II. L is between R and K. Betweeness needs collinearity, which we don't have here. FALSE.

III. R, J and N are coplanar. Any three points lie in some plane. TRUE.

Answer:

56 degrees

Step-by-step explanation:

Because DF is a line that makes it 180 degrees we know that the other two angles on that line are are 60 and 64 now we can make an equation:

We must use one of the trigonometric ratios to find the length, L, of the ramp. If we use 16 as the reference angle, the 22 in would be our opposite side and the ramp length is the adjacent.

Therefore, we must use tan, which is $\frac{opposite}{adjacent}$ :
