Note that the same results are obtained when you use natural functions or logarithms of circular

functions.

opposite angle are known, it is necessary to solve for one of the unknown angles using the sine law.

Next, you will solve for the third angle by subtracting the sum of the given angle and the solved-for

angle from 180. Then, by using the sine law, you can solve for the remaining unknown side.

equals 32 36' 40". Find angles B and C and side c.

B = 21 45' 14" (by natural functions)

Then solve for angle C by subtracting the sum of angles A and B from 180€.

C = 180€-(32€ 36' 40"+21 45' 14") = 125€ 38' 06"
