<span>For a fair coin, the probability of tails is 1/2 or 0.5, so the probability of all tails in 10 tosess is (1/2)^10 = 1/1024 = 0.0009765625 </span>
Answer:
m∠A = 20°
Step-by-step explanation:
Triangle ABC has the following angle measures:
We know that the addition of the angles of a triangle makes 180°, therefore:
m∠A + m∠B + m∠C = 180°
Replacing with data and solving for x:
2x + 5x + 11x = 180
18x = 180
x = 180/18
x = 10°
Which makes the angles:
m∠A = 2*10 = 20°
m∠B = 5*10 = 50°
m∠C = 11*10 = 110°
