Question

Find the length of the missing side. Round answers to the nearest tenth if necessary. 450 92 X

Answer 1

n mathematics, the sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle, to the length of the longest side of the triangle (the hypotenuse).

`\begin{gathered} \sin 45=\frac{x}{9\sqrt[]{2}} \\ x=9\sqrt[]{2}\cdot\sin (45) \\ x=9\sqrt[]{(2})\cdot\frac{\sqrt[]{2}}{2} \\ x=9\cdot(2)/(2) \\ x=9 \end{gathered}`

The answer would be x = 9
