How would you convert the answer for c2 into the actual distance you might measure?

The correct answer is (C) Angle B = 22.5, Angle C = 25.5 and line c = 40.6

Step-by-step explanation: Please refer to the attached diagram for details.

The triangle has been given with angle A measuring 132 degrees and line a measuring 70 units. Angle B is not given but line b measures 36 units. We can apply the sine rule which states that;

a/SinA = b/SinB = c/SinC

Hence, we now have

70/Sin132 = 36/SinB

By cross multiplication we now have

70 (SinB) = 36 (Sin132)

SinB = {36 (Sin132)}/70

SinB = (36 x 0.7432)/70

SinB = 0.3822

By use of calculator or table of values,

B = 22.5 degrees.

To calculate angle C,

Angle C = 180 - (132 + 22.5)

{Sum of angles in a triangle equals 180}

C = 180 - 154.5

C = 25.5 degrees

To calculate line C, having derived angle C,

70/Sin132 = c/Sin25.5

By cross multiplication we now have

70 (Sin25.5) = c (Sin132)

70 x 0.4305 = c x 0.7432

(70 x 0.4305)/0.7432 = c

40.55 = c

c is approximately 40.6

Therefore, Angle B = 22.5, Angle C = 25.5, and line c = 40.6
