Answer 1

Explicación paso a paso:

Relacion entre los 3 sistemas.

Transformando de Centesimal a Sexagesimal.

$\frac{S}{9} = \frac{C}{10} \\ S = \frac{9( {40}^{g})}{10} = \frac{360}{10} = 36$

Transformando de Radial a Sexagesimal.

$\frac{S}{180} = \frac{R}{\pi} \\S = \frac{180( \frac{\pi}{4}) }{\pi} = \frac{180\pi}{4\pi} = 45$

Triangulo

$36 + 45 + x = 180 \\ 81 + x = 180 \\ x = 180 - 81 \\ \boxed{x = 89}$
