### Finding the Angles Practice:

Find the angle for each function. Round off to the nearest 1/2° .
```    Question          Answer

(1) sin  = 0.3745        22°
(2) tan  = 1             45°
(3) cos  = 0.8632        30.5°
(4) sin  = 1             90°
(5) tan  = 0.5785        30°
(6) sin  = 0.7756        51°
(7) cos  = 0.9397        20°
(8) tan  = 1.5030        56.5° ```

### Finding the Angles When Two Sides Are Known: Practice

Find the measurement for both angles of each right triangle. Round off each answer to the nearest 1/2° .
```    Question                      Answer

(1) Opp = 22"       Hyp = 34"          40.5° /49.5°

(2) Adj = 19.375"   Opp = 27.5"        55° /35°

(3) Adj - 64.9375"  Hyp = 78.4375"     34° /56°

(4) Opp = 14.5"     Adj = 29.685"      26° /64°

(5) Hyp = 3'        Opp = 2.5'         56.5° /33.5°
```
