Which number type? I'd go with Whole numbers or integers, since the steps are just whole values one step after the next.
well, an appropriate domain, namely the inputs, well, He's on the 5th step, there are 15 steps, so he's really 10 steps away from the top of the ladder, and going down N being negative, he's -5 steps from the ground.
{ N | N ∈ ℤ , -5 ⩽ N ⩽ 10 }

Explanation:
In this context, a zero is another term for x intercept or root. This is where the graph either touches or crosses the x axis. This occurs in three locations: x = -3, x = 2, and x = 0. So those are the three roots. That makes the first three statements true, while the remaining two others are false.
Side note: x = 0 doesn't always have to be involved. Its quite possible to have x = 0 not be an x intercept. The term "zero" is a bit misleading in that regard. I prefer either "root" or "x intercept" instead.
Answer:
∠ QPR = 56°
Step-by-step explanation:
Δ RST is isosceles ( 2 congruent sides ) , then base angles are congruent
∠ SRT = 
= 
= 68°
∠ PRQ and ∠ SRT are vertically opposite angles and are congruent , so
∠ PRQ = 68°
Δ PRQ is isosceles ( 2 congruent sides ), then base angles are congruent , so
∠ QPR = 
= 
= 56°
