Answer:
∠ ABC = 40°
Step-by-step explanation:
the 3 angles lie on a straight line ABE and sum to 180° , that is
50 - x + 80 + 2x + 40 = 180
x + 170 = 180 ( subtract 170 from both sides )
x = 10
Then
∠ ABC = 50 - x = 50 - 10 = 40°
7 + 2 = 9 and 9/12 + 11/12 = 20/12 = 1 8/12 = 1 2/3
9 + 1 2/3 = 10 2/3
The answer is (A) 2, hope this helps!
Answer:
since there's only 100 students how can 60 participate in sport and 50 participate in music, that must mean there is 110 students right?
