Here y=1/2 x=pi/3=60°

y=cosx
1/2=cos60° and cos60°=1/2

WHAT IS THE VALUE IF X???‼️‼️ HELP ASAP

MaRussiya [10]

The value of x is 40.

Solution:

Given ΔVDG and ΔVNG are similar triangles.

DG = 207, NQ = 138, GQ = 60, QV = x

To find the value of x.

In two triangles are similar, then the measures of the corresponding sides are in proportional to each other.

$$\Rightarrow\frac{DG}{NQ}=\frac{GQ}{QV}$

Substitute the given values.

$$ \Rightarrow\frac{207}{138}=\frac{60}{x}$

Do cross multiplication, we get

$$ \Rightarrow{207\times x}=138\times60$

$$ \Rightarrow{207\times x}=8280$

Divide by 207 on both sides of the equation, we get

$$ \Rightarrow x=\frac{8280}{207}$

$$ \Rightarrow x=40$

Hence the value of x is 40.

Find the surface area of this cube 7m 7m 7m. Be sure to include the correct unit in your answer.

7nadin3 [17]

Answer:

294 $m^2$

Step-by-step explanation:

The area of one face of the cube would be 7 x 7 = 49 $m^2$

Since there are 6 faces on a cube, the total surface area would therefore be 49 x 6 = $294m^2$
