Fresh day unabantu, let's solve.

When $\theta = 40^\circ$ is fixed, any triangles formed by different positions of A will be similar triangles. For similar triangles, the ratios of corresponding sides are always constant. Therefore, the ratios $\frac{CA}{BC}$ , $\frac{BA}{BC}$ , and $\frac{CA}{BA}$ will remain constant, regardless of the size of triangle ABC. These constant ratios are the trigonometric ratios for an angle of $40^\circ$ .

Fresh day unabantu, let's solve. When = 40^ is fixed, any triangles formed by different positions of A will be similar triangles. For similar triangles, the ratios of corresponding sides are always constant. Therefore, the ratios (CA)/(BC), (BA)/(BC), and (CA)/(BA) will remain constant, regardless of the size of triangle ABC. These constant ratios are the trigonometric ratios for an angle of 40^. What's next? 📸
