<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

Hope this helps!

(2^x+y , 3^x-y )= (16,9) find the value of x and y
Jet001 [13]

Answer:

x=3,y=1

Step-by-step explanation:

2^x+y=16,3^x-y=9

16=2^4,9=3^2

x+y=4,x-y=2 add both

2x=6,x=3

3-y=2,y=1

The rectangle shown has a perimeter of 146 cm and the given area. Its length is 7 more than five times its width. Write and solv
dangina [55]

Answer:

System of equations:

L = 5W + 7

2W + 2L = P

L = 62 cm

W = 11 cm

Step-by-step explanation:

Given the measurements and key words/phrases in the problem, we can set up two different equations that can be used to find both variables, length and width, of the rectangle.  

The formula for perimeter of a rectangle is:  2W + 2L = P, where W = width and L = length.  We also know that the L is '7 more than five times its width'.  This can be written as:  L = 5W + 7.  Using this expression for the value of 'L', we can use the formula for perimeter and solve for width:

2W + 2(5W + 7) = 146

Distribute:  2W + 10W + 14 = 146

Combine like terms:  12W + 14 = 146

Subtract 14 from both sides:  12W + 14 - 14 = 146 - 14 or 12W = 132

Divide 12 by both sides:  12W/12 = 132/12 or W = 11

Put '11' in for W in the equation for 'L':  L = 5(11) + 7 or L = 55 + 7 = 62.
