The missing sides are of the given triangle are of 26.69 units and 11.33 units.
Missing sides of the triangle.
The sine trigonometric ratio gives us ratio of perpendicular to hypotenuse from perspective of the considered angle.
Referring to the figure attached below,
[tex]sin(\angle ACB)= \dfrac{AB}{AC}\\\\sin(67^\circ) = \dfrac{AB}{29}\\\\0.9205 \times 29 = AB\\\\AB = 26.69\\[/tex]
Similarly,
[tex]cos(\angle ACB)= \dfrac{BC}{AC}\\\\cos(67^\circ) = \dfrac{BC}{29}\\\\0.3907 \times 29 = BC\\\\BC = 11.33\\[/tex]
Thus, the missing sides are of the given triangle are of 26.69 units and 11.33 units.
