Answer:
Step-by-step explanation:
The sample is his friends. They might be the same group of interests. The sample needs to be random. Even if he went around and grabbed random people he may not have known at his school, it still wouldn't be random bc they could all be bias towards a local sports team or have different interests than someone from somewhere else

Answer:
A) ∠DHG = 96°
B) arc EF = 134°
Step-by-step explanation:
<u>Part A</u>:
As you have shown in your work, angle DHG is supplementary to given angle FHG:
∠DHG = 180° -∠FHG
∠DHG = 180° -84°
∠DHG = 96°
__
<u>Part B</u>:
∠DHG is half the sum of arcs EF and DG.
96° = (1/2)(arc EF + 58°) . . . . . fill in known values
192° -58° = arc EF . . . . . . . . . . multiply by 2, subtract 58°
arc EF = 134°
