9. Pardekooper   Solve right triangle ABC if b=32,  A=25 o, and  C=90 o a b=32 c = 25 o = 90 o The sum of the angles of a triangle is 180 o. = 65 o A B C a c b AA BB CC  A+  B+  C = 180 o. 25 o +  B+90 o = 180 o.  B+115 o = 180 o  B = 65 o 65 o 32

10.   Solve right triangle ABC if b=32,  A=25 o, and  C=90 o a b=32 c = 25 o = 90 o = 65 o A B C a c =15 32 AA BB CC Pardekooper tan  = opposite adjacent tan25 0 = a 65 o 32 32   32 32tan25 0 = a 15 = a 15

11.   Solve right triangle ABC if b=32,  A=25 o, and  C=90 o a b=32 c = 25 o = 90 o = 65 o A B C c =15 32 AA BB CC Pardekooper We will find c tomorrow 65 o 15

12.  Now lets find  A  to the nearest degree.  C Pardekooper tan  = opposite adjacent tan  = 11 7 7  = tan -1 11 7  = 58 0

13.  Now lets find  B  to the nearest degree.  C Pardekooper tan  = opposite adjacent tan  = 11 7 7  = tan -1 7 11  = 32 0
