Problem : Solve the following right triangle, in which C = 90 o : a = 6 , B = 40 o .

A = 90 o - B = 50 o . b = a tan(B) 5.0 . c = 7.8 .

Problem : Solve the following right triangle, in which C = 90 o : b = 6 , c = 8 .

a = 5.3 . A = arcsin() 41.4 o . B = 90 o - A 48.6 o .

Problem : Solve the following right triangle, in which C = 90 o : A = 40 , B = 50 .

This triangle cannot be solved. Three angles is not sufficient information to determine a unique triangle.

Problem : Solve the following right triangle, in which C = 90 o : b = 6 , B = 72 o .

A = 90 o - B = 18 o . a = b tan(A) 1.9 . c = 6.3 .

Problem : Solve the following right triangle, in which C = 90 o : c = 41 , A = 20 o .

B = 90 o - A = 70 o . a = c sin(A) 14.0 . b = 38.5 .

Problem : Solve the following right triangle.

c = = 10 . B = arctan() 36.9 o . A = 90 o - B 53.1 o .

Problem : Solve the following right triangle.

B = 90 o - A = 75 o . a = b tan(A) .8 . c = 3.1 .

Problem : Solve the following right triangle.

A = 90 o - B = 52 o . b = c cos(A) 4.8 . a = 6.1 .
