Answer:

1. x + y = 25

2. x - y = 7

3. x = 16, y = 9

Step-by-step explanation:

(x + y = 25) + (x - y = 7)

2x (the y cancels) = 32

32/2 = 16, x = 16

substitute x in either equation

16 + y = 25

y = 9

Please help me find the value of x

Mandarinka [93]

Answer:

$10 \sqrt{3}$

Step-by-step explanation:

<h2>Given Question, </h2>

To find the value of x.

<h2>Solution:</h2>

According to Pythagoras Theorem-

${20}^{2} = {10}^{2} + {x}^{2}$

$= > 100 + {x}^{2} = 400$

$= > {x}^{2} = 400 - 100$

$= > {x}^{2} = 300$

$= > x = \sqrt{300}$

$= > x = 10 \sqrt{3}$

<h2>Result:</h2>

Hence, the required value of x is 

 $10\sqrt{3}$
