• Right Triangles only

• Never

Set up the problem...

• sin X = 41/28

• tan X = 41/28

• cos X = 28/41

• sin X = 28/41

Solve the right triangle.

• <B = 39^o, AB = 11.58, AC = 7.29

• <B = 39^o, AB = 7.29, AC = 11.58

• <B = 129^o, AB = 11.58, AC = 7.29

• <B = 129^o, AB = 7.29, AC = 11.58

Solve the right triangle.

• <A = 34^o, <C = 56^o, AC = 5.59

• <A = 56^o, <C = 34^o, AC = 5.59

• <A = 34^o, <C = 56^o, AC = 9.01

• <A = 56^o, <C = 34^o, AC = 9.01
