Anna71 [15]

Answer:

A. x-6

Step-by-step explanation:

Maybe you want to simplify ...

((6x)/(10x^2))/(6/(10x^3 -60x^2))

Invert and multiply. Cancel common factors from numerator and denominator.

$\dfrac{\left(\dfrac{6x}{10x^2}\right)}{\left(\dfrac{6}{10x^3-60x^2}\right)}=\dfrac{6x}{10x^2}\cdot\dfrac{10x^3-60x^2}{6}=\dfrac{6\cdot10x^2}{6\cdot10x^2}(x-6)\\\\=\boxed{x-6}$

See the attached picture to better understand the problem

we know that
in the right triangle ABC
sin 63°=AB/BC
AB is the opposite side angle 63-----> x cm
BC is the hypotenuse-----> 85 cm
AB=BC*sin 63°-----> AB=85*sin 63-----> AB=75.736 cm
AB=75.8 cm

the answer is
the value of x is 75.8 cm
