Answer:

Step-by-step explanation:

For angle C,

cos(∠C) = \frac{\text{Adjacent side}}{\text{Hypotenuse}} = 0.97

sin(∠C) = \frac{\text{Opposite side}}{\text{Hypotenuse}} = 0.26

tan(∠C) = \frac{\text{Adjacent side}}{\text{Adjacent side}} = 0.27

Therefore, from the triangle ABC,

cos(∠A) = cos(90° - ∠C)

             = sin(∠C)

             = 0.26

sin(∠A) = sin(90 - ∠A)

            = cos(∠A)

            = 0.97

tan(∠A) = \frac{\text{sinA}}{\text{cosA}}=\frac{0.97}{0.26}

            = 3.73

Angle        \frac{\text{Adjacent side}}{\text{Hypotenuse}}                 \frac{\text{Opposite side}}{\text{Hypotenuse}}                    \frac{\text{Opposite side}}{\text{Adjacent side}}

  A                    0.26                       0.97                             3.73

Ok so from experience on this site
3x2=3x^2
people don't know how to put exponents
3x^2-y^3-y^3-z
simplify first

3x^2-2y^3-z

x=3
y=-2
z=-5

Answer:

21°

Step-by-step explanation:

the angles of triangle abc has to = 180 so subtract the known angles to get 21

angles bca and daf have to be the same so its 21

Suppose it costs $43 to roll a pair of dice. you get paid $6 times the sum of the numbers that appear on the dice. is it a fair
lutik1710 [3]

The game is not fair as 6 times the expected sum is less than the cost, $43.

In the question, we are asked if the game is fair.

For the game to be fair, 6 times the expected sum for the pair from the game has to be greater than or equal to $43, that is,

6E(X) ≥ 43.

The expected sum for the pair, E(X) can be calculated using the formula,

E(X) = ∑x.p(x),

or, E(X) = 1/18 + 1/6 + 1/3 + 5/9 + 1/6 + 7/9 + 10/9 + 1 + 5/6 + 11/18 + 1/3,

or, E(X) = 107/18.

Now, 6E(X) = 6*(107/18) = 107/3 = 35.67.

Since, the total return from the game is $35.67, which is less than the cost of $43, the game is not fair.
