Answer:
Step-by-step explanation:
The diagram of the triangle is shown in the attached photo. Since the length of two sides and one angle is known, we will apply the sine rule. It states that
a/sin A = b/sin B = c/sin C
From the triangle
b = 12
c = 18
12/sin 28 = 18/sinC
Cross multiplying
12SinC = 18sin28
12SinC = 18×0.4695
12sinC = 8.451
SinC = 8.451/12 = 0.70425
C = Sin^-1(0.70425) = 44.77
Since the sum of the angles in a triangle is 180 degrees,
Angle A = 180 - 28 - 44.77 = 107
Therefore, the following statements are true
There is only one possible value for the measure of the largest angle of the triangle, 107°.
