Answer:

D

Step-by-step explanation:

  • You have 5 + 6 pencils, which is 11 pencils
  • The probability you will get white is 5/11
  • Prob you get red is 6/11
  • If you pick up a pencil and do not replace it, you now only have 10 pencils left
  • The prob you get a red or a white is dependent on what you picked up first

Can somebody anybody please help me with this math problem?
Annette [7]

Answer:

30°

Step-by-step explanation:

Angle C = 55°, Angle D = Angle A = 65°, Angle B = 2x

Sum of angles in a triangle = 180°

65° + 55° + 2x = 180

120 + 2x = 180

2x = 180 - 120

2x = 60

x = 30°
