Answer:

Step-by-step explanation:

First, put 3(sqrt(6)) in a different form:

sqrt(9) * sqrt(6) = sqrt(54)

We know that a 30 60 90 triangle has a horizontal leg equal to 1, a vertical leg equal to sqrt(3), and a hypotenuse equal to 2.

Find a multiplier/ratio with this information:

(sqrt(54))/(sqrt(3)) = sqrt(18)

given value/accepted value = multiplier

Now, multiply the other values by the multiplier:

1*sqrt(18) = sqrt(18) or 3(sqrt(2))

2*sqrt(18) = 2(sqrt(18)) or 6(sqrt(2))

Your answer would be:

x = 3(sqrt(2))

y = 6(sqrt(2))

Or option B.

LAW OF SINES ANYONE?? need good explanation..ill give brainlest

Dominik [7]

Step-by-step explanation:

So i will try to explain it:

Scientists in the past invented this formula and theory of sines:

$\frac{a}{ \sin(a) } = \frac{b}{ \sin(b) } = \frac{c}{ \sin(c) }$

So the only thing is to put the given numbers into this formula :)

The task that i've just done is like this:

$\frac{a}{ \sin(a) }$

a is the numerator,that is delighted in the triangle,well its transparent.

What about denominator?

Here is the tip:

opposite to A- side angle-a has to be put into sin(a)

sin- how to calculate?

Easy just take the trigonometric functions formula or calculate in scientific calculator that's it.

$\frac{a}{ \sin(a) } = \frac{b}{ \sin(b) }$

one of this numbers might be unknown in that case solve by proportion(equation).

Carefully contemplate my answer in the media.

I hope you understood.

Good luck!

The heights of 10 year old children has a normal probability distribution with mean of 54.6 inches and standard deviation of 5.7

Fofino [41]

Answer:

a) 0.69

The probability that a randomly selected 10-year old child will be more than 51.75 inches tall

P(X>51.75 ) = 0.6915

Step-by-step explanation:

Step(i):-

Given mean of the Population = 54.6 inches

Given standard deviation of the Population = 5.7 inches

Let 'X' be the random variable of normal distribution

Let 'X' = 51.75 inches

$Z = \frac{x-mean}{S.D} = \frac{51.75-54.6}{5.7} = -0.5$

Step(ii):-

The probability that a randomly selected 10-year old child will be more than 51.75 inches tall

P(X>51.75 ) = P(Z>-0.5)

= 1 - P( Z < -0.5)

= 1 - (0.5 - A(-0.5))

= 1 -0.5 + A(-0.5)

= 0.5 + A(0.5) (∵A(-0.5)= A(0.5)

= 0.5 +0.1915

= 0.6915

Conclusion:-

The probability that a randomly selected 10-year old child will be more than 51.75 inches tall

P(X>51.75 ) = 0.6915
