plz give the answer fast​

Answer 1

Answer:

Hope it helps.....

Step-by-step explanation:

$\sqrt{ {9}^{2} - {15}^{2} } = x$

$\sqrt{81 - 30} = x$

$\sqrt{51} = x$

$x = 7.1$

Answer 2

Answer:

x = 12

Step-by-step explanation:

By pythogoras theorem

(Hypotenuse)² = ( side )² + ( side )²

( 15 )² = ( x )² + ( 9 )²

225 = ( x )² + 81

225 - 81 = ( x )²

( x )² = 144

x. = ± √ 144

x. = ± 12

Since side can't be neagtive we have to consider the positive values only..

Therefore ; x = 12
