sin =  \frac{opp}{hyp}

\sin(60)  =   \frac{opp}{4}

opp = 3.464101615

The length of QR is 3.5

//

{c}^{2}  -  {b}^{2}  =  {a}^{2}

{4}^{2}  -  {3.464101615}^{2}  =  {4.000.......}^{2}

\sqrt{4.000.......}  = 2

The length of PQ is 2

The areas of the squares adjacent to two sides of a right triangle are 32units^2 and 32 units^2
adoni [48]

Answer:

x = 8 units.

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

<em>The areas of the squares adjacent to two sides of a right triangle are 32 unit square and 32 units square. Find the length,x, of the third side of the triangle</em>

My answer:

  • Let a is the side length of the 1st square

The area of the 1st square is equal to 32 units square

<=> a^{2} = 32

<=> a = 4\sqrt{2} units

  • Let b is the length  of the 2nd  square

The area of the 2nd square is equal to 32 units square

<=> b^{2} = 32

<=> b = 4\sqrt{2} units

  • Find the value of x

Applying the Pythagoras Theorem, we have:

x^{2} = a^{2} + b^{2}

<=> x^{2}  = 32 + 32  

<=> x^{2} = 64

<=> x = 8 units

Hope it will find you well.

What is the volume of a cylinder, in cubic ft, with a height of 9ft and a base diameter
aev [14]

Answer:

Volume of cylinder is: Volume=1808.64 ft³

Step-by-step explanation:

Height of cylinder = 9 ft

Base diameter of cylinder = 16 ft

We need to find volume of cylinder .

The formula used is: Volume=\pi r^2h

We need radius:

The radius = diameter/2 = 16/2 = 8 ft

Putting values and finding volume of cylinder

Volume=\pi r^2h

Volume=3.14\times (8)^2\times (9) \\Volume=3.14\times 64\times (9) \\Volume=1808.64 \: ft^3

So, Volume of cylinder is: Volume=1808.64 ft³

a recipe for pie crust calls for 2/3 cups of flour. a chef is making 1/2 of the recipe. how much flour should the chef use?
natka813 [3]

Answer:

1/3 cups of flour

Step-by-step explanation:

The recipe originally calls for 2/3 cups of flower.  However, if the chef only wants to make <u>half</u> of the recipe, we must divide the original recipe by 2.  Dividing by 2 is the same as multiplying by 1/2.

2/3 * 1/2 = 2/6 (multiply across)

Simplify 2/6 - 1/3.

Show that solving the equation 3^2x=4 by taking common logarithms of both sides is equivalent to solving it by taking logarithms
Sophie [7]

Answer:

Step-by-step explanation:

Case I:  use common logs:

 2x log 3 = log 4, or 2x(0.47712) = 0.60206

 Solving for x, we get 0.95424x = 0.60206, and then x = 0.60206/0.95424.

 x is then x = 0.631

Case II:  use logs to the base 3:

 2x (log to the base 3 of 3) = (log to the base 3 of 4)

 This simplifies to 2x(1) = 2x = (log 4)/log 3 = 1.262.  Finally, we divide this

 result by 2, obtaining x = 0.631
