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.

Which of the following is a proper fraction 7/6 4/3 1/2 3/3
larisa86 [58]
1/2 because 7/6 & 4/3 are improper fractions(fractions that have a higher numerator than a denominator) and 3/3 should just be written as 1.

The measure of an angle is seventy-one times the measure of a supplementary angle. What is the measure of each angle?
steposvetlana [31]

Let the smallest angle = x

Then the larger one = 71x

Supplementary angles are always equal to 180o

x + 71x = 180o Add the left side

72x = 180 Divide by 72

x = 180/72

x = 2.5

The smallest angle = 2.5 degrees

The largest angle = 2.5 * 71

The largest angle= 177.5 degrees.
