Problems from Trigonometric Ratios: sine, cosine and tangent

Development:

First, we define how long each side of the triangle is:

$$\overline{AB}=5\overline{AC}=4\overline{BC}=3$$

Then, once the length of every side is calculated, we proceed by computing the trigonometric ratios that have been told to:

1. $\sin (x)={\displaystyle \frac{3}{5}}=0.6$
2. $\cos (x)={\displaystyle \frac{4}{5}}=0.8$
3. $\tan (x)={\displaystyle \frac{3}{4}}=0.75$

Solution:

1. $\sin (x)=0.6$
2. $\cos (x)=0.8$
3. $\tan (x)=0.75$
