The best design for this study would be a CENSUS. This is the best design for the study if the City of Atlanta council wants to know whether the residents are in favor of the beautification of the downtown area. So basically, in a census, a survey of the population is being conducted and this kind of survey usually focuses on the preferences of the individuals of that population.
Answer:
B
Step-by-step explanation:
∠ 2 and 37° are vertically opposite angles and are congruent, then
∠ 2 = 37°
∠ 1 and 37° are a linear pair and sum to 180° , that is
∠ 1 + 37° = 180° ( subtract 37° from both sides )
∠ 1 = 143°
∠ 1 and ∠ 3 are vertically opposite angles and are congruent , then
∠ 3 = 143°
Answer:
FE = 30°
Step-by-step explanation:
arc FGC = arc FG + arc GB + arc BC
220° = 90° + arc GB + 70° . . substitute known values
60° = arc GB . . . . . . . . . . . . . subtract 160°
__
External angle A is half the difference of arcs EG and GB:
30° = (1/2)(arc FE +90° -60°) . . . substitute known values
60° = arc FE + 30° . . . . . . . . . . . multiply by 2 and simplify
30° = arc FE . . . . . . subtract 30°
_____
The key to this problem is the relationship between external angle A and the measures of the arcs it subtends.
