I think the answer may be D. You can graph the points and draw a line through the points to see what other points are intersected by the line.
H=how far up from the ground does the ladder touch the building
h/30=sin 25°
h=30 sin 25°
h=12.7 decimeters(1 decimal place)
Answer: The height that the ladder touch the building far up from the ground is 12.7 decimeters.
The domain and the range is [-6 to +inf)
