The length is 46.10 cm.
Since ∠BCA = 50.5°, ∠ACD = 180-50.5 =129.5°. This means that ∠CAD = 180-(129.5+35.8) = 14.7°. We can now use the law of sines;
sin 14.7/20 = sin 35.8/x
Cross multiply:
x*sin 14.7 = 20*sin 35.8
Divide both sides by sin 14.7:
x = (20*sin 35.8)/(sin 14.7) = 46.10
The probability of rolling a 5 and rolling an odd number on a die is independent; rolling a 5 does not influence the probability of rolling an odd number the next time.
King or Jack is mutually exclusive; they cannot both happen at the same time.
Club or Queen is not mutually exclusive; they can happen at the same time.
King or Ace is mutually exclusive; they cannot both happen at the same time.
Answer:
I can't see the picture.
Step-by-step explanation:
distribute and simplify if needed, see what you get
1 mile ≈ 1.6 km
5.067 km ≈ 5.067÷1.6 ≈ 3.2 miles
time travelled = distance ÷ speed
time travelled = 3.2÷225
time travelled = 0.0142 hour = 51.2 seconds
