Given triangle is a right angle triangle so we are allowed to use trigonometric formulas.

We want to find Hypotenuse using angle A and base 7 cm

so right choice is to use cosine

$\cos(A)=\frac{AC}{AB}$

$\cos(25^{\circ})=\frac{7}{AB}$

$0.90631=\frac{7}{AB}$

$AB=\frac{7}{0.90631}$

$AB=7.72362657369$

Hence value of side AB is approx 7.72 cm.

F(x) = [[x]], what is f(9)?

Inga [223]

Okay so in this expression, the variable x is set to 9.

Because this expression is just x = x, whatever the value of x is will be the same for both x's.

So, f(9) = 9
