Determine the missing angles
Since AB = AD, then:
--- Base angles of an isosceles triangle
Hence:
--- angles in a triangle
Collect Like Terms
--- angle on a straight line
Since ABC is isosceles, then:
--- base angle of isosceles
Lastly:
<em>See attachment</em>
Number of tails(21) / Total times flipped (45) = ~0.466667%
Chance of tails(~0.466667%) times total times flipped( 15) = 6.99999999…=7
Basically just find the percent of tails and use that percent for the different amount of times the coin will be flipped.
Answer: 7
I am almost positive that the answer is B. This is because the exponents are decreasing as you go right
