Answer:

x=31.6

Im not sure since i have not taken a trig course yet, but i know the basics:

Tangent is opposite over adjacent, and in respect to this angle, (31 degrees) the opposite side is 19 and adjacent is x.

Tan(31) = 19/x

Solve for x...use a calculator to find tan(31)

Max tossed a fair coin 3 times. What is the probability of getting heads in the first two trials and tails in the last trial?

Whitepunk [10]

When you toss a coin 3 times here is what can happen:
H=heads
T= Tails
HHH TTT
<u>HHT</u> TTH
HTH THT
HTT THH
Since 8 things can happen and only one of them is what you want, the probability is 1/8
Another way to think about it is each toss has 1/2 of coming up as you want it to.
Three tosses are 1/2 x 1/2 x 1/2 which is 1/8
