Question

What will be the number of students that obtained a D

Answer 1

Answer:

75°

Step-by-step explanation:

complete angle =360°

60°+105°+120°+x=360°

285°+x=360°

x=360°-285°

x=75°

Answer 2

Answer:

Angle for D : 360 - (60 + 105 +120) = 360 - 285 = 75°

Percentage of 75 out of 360 : (75/360) × 100 = 20.83 %

20.83 % of 120 = 25 students
