$\sf \leadsto \cos(45) \degree = (25)/(x)$

$\\$

$\sf \leadsto (1)/( √(2) ) = (25)/(x)$

$\\$

squaring both sides:

$\sf \leadsto (1)/( 2 ) = \frac{625}{x {}^(2) }$

$\\ \\$

$\sf \leadsto {x}^(2) = 625 * 2$

$\\$

$\sf \leadsto {x}^(2) = 1250$

$\\ \\$

$\sf \leadsto {x} = √(1250)$

$\\ \\$

$\sf \leadsto {x} = 35.355 \{approx \}$
