In triangle ABC, the measure of angle B is 44 degrees more than three times the measure of angle A. The measure of angle C is 61
degrees more than the measure of angle A. Find the measure of each angle
1 answer:
Answer:
m∠A = 15°; m∠B = 89°; m∠C = 76°
Step-by-step explanation:
The sum of the three interior angles of a triangle is 180°.
Let x = m∠A
Then 3x + 44 = m∠B
and x + 61 = m∠C
x + 3x + 44 + x + 61 = 180
5x + 105 = 180
5x = 75
x = 15
m∠A = 15°
m∠B = 3(15) + 44 = 45 + 44 = 89°
m∠C = 15 + 61 = <u> 76°</u>
Sum = 180°

Answer:
The expected payout of the game is $230.46.
Step-by-step explanation:
The given table is
Payout Amount : $160 $4400 $145000
Probability : 0.146 0.024 0.0007
We need to find the expected payout of the game.
The formula for expected payout is
where, n is amount and P(x) is probability of that event. The value of n is negative for loss.
Using the above formula we get
Therefore the expected payout of the game is $230.46.
