Answer:

x = \sqrt{3}

Step-by-step explanation:

Using the tangent ratio in the right triangle and the exact value

tan60° = \sqrt{3} , then

tan60° = \frac{opposite}{adjacent} = \frac{3}{x} = \sqrt{3} ( multiply both sides by x )

3 = x × \sqrt{3} ( divide both sides by \sqrt{3} )

\frac{3}{\sqrt{3} } = x , then rationalising the denominator

x = \frac{3}{\sqrt{3} } × \frac{\sqrt{3} }{\sqrt{3} } = \frac{3\sqrt{3} }{3} = \sqrt{3}

x = \sqrt{3}

Step-by-step explanation:

Given:

\sin(ABC) =  \frac{AC}{AB}

=  >  \sin(60) =  \frac{3}{AB}

=  >AB= 2 \sqrt{3}

Now by Pythagoras theorem,

AC^{2} + BC^{2} = AB^{2}

Substituting values,

{3}^{2} +  {x}^{2} = (2 \sqrt{3})^{2}

=  >  {x} =  \sqrt{3}

Hence, value of x is \sqrt{3}

Multiply Conjugates Using the Product of Conjugates Pattern
weeeeeb [17]

Answer:

The product is the difference of squares is $$\left(xy-9\right)\left(xy+9\right)={{x}^2}{{y}^2}-81$$

Step-by-step explanation:

Explanation

  • The given expression is (x y-9)(x y+9).
  • We have to multiply the given expression.
  • Square the first term xy. Square the last term 9 .

$$\begin{aligned}&(x y-9)(x y+9)=(x y)^{2}-(9)^{2} \\&(x y-9)(x y+9)=x^{2} y^{2}-81\end{aligned}$$

andrew-mc [135]
As the sine rule states,

A/sina = B/sinb = C/sinc .

in the diagram, there are two identified sides and if you use the sine rule, you can find the opposed angles easily.

there are:

side a, with angle â .
side b, with angle b.

so the answer is C.

if you input these into the sine rule, it would be:

a/ sin a = b/sin b

Given: PRST square
yuradex [85]
There is no difficulty in this problem until you construct the figures. How can we do it is shown in the attached picture. After drawing PRST, from the point P, we can draw PMKD and later we can complete PMCT as a result. From this picture, we can see that the side of PMCT is also a. Then, the area of this square is A=a^{2}
