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.

1.)Painting Jane is painting one wall of her living room. The wall is rectangular, 13 feet wide by 9 feet high. What is the area

antiseptic1488 [7]

Answer:

1. $117 ft^{2}$

2. $54 ft^{2}$

3. $1,428 ft^{2}$

4. $644 ft^{2}$

5. $4,700 ft^{2}$

6. $57,600 ft^{2}$

Step-by-step explanation:

First use $A = w*l$

$w = width$

$l = length$

It doesn't have to be $A = w*l$ , it could be $A = l*w$ . It will be the same answer.

1. $3 ft * 9 ft = 117 ft^{2}$

2. $3 ft * 18 ft = 54 ft^{2}$

3. $42 ft * 34 ft = 1,428 ft^{2}$

4. $23 ft * 28 ft = 644 ft^{2}$

5. $94 ft * 50 ft = 4,700 ft^{2}$

6. $360 ft*160 ft = 57,600 ft^{2}$
