∠A = 180° - (63°+101°)=16°

sine's rule

\tt \dfrac{AB}{sin~C}=\dfrac{BC}{sin~A}\\\\\dfrac{AB}{sin~63}=\dfrac{9}{sin~16}\\\\AB=29.09

Answer:

AB = 29

Step-by-step explanation:

Law of Sines:

\frac{9}{sin 16} = \frac{x}{sin 63}

cross-multiply:

x·sin(16°) = 9·sin(63°)

x = \frac{9sin63}{sin16}

x = 29

You roll two fair dice, one green and one red. (a) Are the outcomes on the dice independent? Yes No (b) Find P(1 on green die an
ASHA 777 [7]

Answer:

a

  Yes

b

 P(1 \& 5) = \frac{1}{36}

c

 P(5 \& 1) = \frac{1}{36}

d

 P(5 \& 1 | 1\& 5  ) = \frac{1}{18}

Step-by-step explanation:

From the question we are told that

     Two fair dice, one green and one red were rolled

Generally the  outcomes on the dice independent because the outcome on the first dice is not affected by the second die

Generally the  probability of getting a 1  on a dice rolled is  P(1) =  \frac{1}{6}

the  probability of getting a 5 on a dice rolled is  P(5) =  \frac{1}{6}

Generally the probability of P(1 on green die and 5 on red die) is mathematically represented as

         P(1 \& 5) = \frac{1}{6}  *\frac{1}{6}

         P(1 \& 5) = \frac{1}{36}

Generally the probability of P(5 on green die and 1 on red die) is mathematically represented as

          P(5 \& 1) = \frac{1}{6}  *\frac{1}{6}

         P(5 \& 1) = \frac{1}{36}

Generally the probability of P((1 on green die and 5 on red die) or (5 on green die and 1 on red die)) is mathematically represented as

          P(5 \& 1 | 1\& 5  ) = \frac{1}{36} + \frac{1}{36}

         P(5 \& 1 | 1\& 5  ) = \frac{1}{18}

Over [174]

Answer:

y=1/2 x -2 is the perpendicular line equation

Step-by-step explanation:

y=1/2 x + b

solving for b:

Solve for y<br> 4y + 8 = 29 - 5y
andriy [413]

Answer:

7/3

Step-by-step explanation

4y+8=29-5y

First you are going to subtract 8 from both sides of the equation.

4y=21-5y

Next you are going to add 5y to each side of the equation.

9y=21

Now write it as a fraction,

9/21

Last but not least simplify.

3/7
