Solve for X : (24)^2 - (7+x)^2 = 13^2 - x^2​

Answer» ONG>Answer:

25.57

Step-by-step EXPLANATION:

Q. (24)^2 - (7+x)^2 = 13^2 - x^2

Soln. :- (24)^2 - (7+x)^2 = 13^2 - x^2

or, 576- {(7)^2 + x^2 + 2 X 7 X x} = 169 - x^2

or, 576 - { 49 + x^2 + 14x} = 169 - x^2

or, 576 - 49 - x^2 - 14x = 169 - x^2

or, 527 - x^2 - 14x = 169 - x^2

or, - x^2 - 14x + x^2 = 169 - 527

or, - 14x = - 358

or, x = - 358 ÷ -14

or, x = 25.57
