Lesson 28.2

$$\frac{15}{8}$$  

$$\frac{17}{8}$$  

$$\frac{8}{17}$$  

$$\frac{15}{17}$$  

30-60-90

45-45-90

20-70-90

40-50-90

$$\sin\left(37^{\circ}\right)=\frac{x}{14}$$

$$\cos\left(37^{\circ}\right)=\frac{x}{14}$$

$$\tan\left(37^{\circ}\right)=\frac{x}{14}$$

$$\sin\left(37^{\circ}\right)=\frac{14}{x}$$

$$\sin\left(A\right)=\frac{10}{14}$$

$$\cos\left(A\right)=\frac{10}{14}$$

$$\tan\left(A\right)=\frac{10}{14}$$

$$\tan\left(A\right)=\frac{14}{10}$$

$$A=\sin^{-1}\left(\frac{10}{14}\right)$$

$$A=\cos^{-1}\left(\frac{10}{14}\right)$$

$$A=\tan^{-1}\left(\frac{10}{14}\right)$$

$$A=\tan^{-1}\left(\frac{14}{10}\right)$$

$$\sin^{-1}\left(\frac{15}{16}\right)$$

$$\cos^{-1}\left(\frac{15}{16}\right)$$  

$$\tan^{-1}\left(\frac{15}{16}\right)$$  

Good question
