<h2><u>Question :-</u></h2>

Find AD.

\sf a. \:  2\sqrt{3}  \: m

\sf b. \: 3 \sqrt{3}  \: m

\sf c. \: 6 \: m

\sf d. \: 6 \sqrt{3}

____________________

<h2><u>Solution :-</u></h2>

<h3><u>Given Information :-</u></h3>

  • ∠DCB = 30°
  • ∠BDC = 90°
  • ∠ABC = 90°
  • BC = 12 m

<h3><u>To Find :-</u></h3>

  • The Length of AD

<h3><u>Calculation :-</u></h3>

Here, Sin θ is 30°

Sin = \bf \frac{perpendicular}{hypotenuse}

Here, θ is 30°

<em><u>Substituting the values, We get, </u></em>

∴ Sin ( 30 ) = \sf \frac{AD}{BC}

<em><u>Substituting the value of BC as 12, We get, </u></em>

⇒ Sin ( 30 ) = \sf \frac{AD}{12}

<em><u>Transposing 12 to Left Hand Side, We get, </u></em>

⇒ Sin ( 30 ) × 12 = AD

<em><u>Calculating further, We get, </u></em>

⇒ AD = 6 m

∴ AD = 6 m

<h3>____________________</h3>

<h2><u>Final Answer :-</u></h2>

The Length of AD is 6 m

Answer:

AD = 6m

Step-by-step explanation:

Sin(30) = AD / 12

Sin(30) * 12 = AD

6 = AD

a red ball and 4 white ball are in a box if two balls are drawn without replacement ,what is the probability of getting a red ba
BARSIC [14]

The probability is 1/5 to get a red ball in 1st draw and a white ball in 2nd draw.

<u>Step-by-step explanation:</u>

  • There are 1 red ball and 4 white balls in a box.
  • The total number of balls in the box = 1 red + 4 white = 5 balls.

The two balls are drawn without replacement.

<u>Drawing the first ball :</u>

The first draw should be a red ball.

The probability to get a red ball = No.of red balls / Total balls in the box.

We know that, No. of red balls is 1 and total balls in the box is 5.

P(red ball) = 1/5

<u>Drawing the second ball :</u>

The second draw should be a white ball.

The probability to get white ball = No.of white balls / Total balls in the box.

We know that,

No. of white balls is 4.

The total balls in the box after the first draw will be 4 balls.

P(white ball) = 4/4

The probability of getting a red ball on the first drawn and a white ball on the second​ draw = P(red ball) × P(white ball)

⇒ (1/5) × (4/4)

⇒ 4/20

⇒ 1/5

Therefore, the probability is 1/5 to get a red ball in 1st draw and a white ball in 2nd draw.

Draw a pair of adjacent supplementary angles so that one has a measure of 15 degrees
Nat2105 [25]

Answer:

the best way to to do this would be to use a protractor, if you don't have one you would have to guess on the 15 degrees, but it would be a very small angle
