19/20
19/20 = 0.95
0.9 < 0.95
Radius = circumference/2(3.14)
OPTION 3
Answer:
209.96
Step-by-step explanation:
we know that the circumference of the circle is equal to
C = 
we have

substitute would be

assume that 
64
Answer:
60°
please look into the solution down here.
Step-by-step explanation:
since BD bisects it, then the angles should be bisected symmetrically, or in other words, ANGLE ABD = angle DBC,
hence,
4x = 2x +30
2x = 30
x = 15
therefore, angle DBC = 2x + 30 = 2(15) + 30 = 60°.
