Use the Law of Sines to complete an expression that represents the angle measure x.

The sine rule is used when we are given either a) two angles and one side, or b) two sides and a non-included angle. The cosine rule is used when we are given either a) three sides or b) two sides and the included angle. Study the triangle ABC shown below.

Step-by-step explanation:

Sine rule ; a/Sin A = b/Sin B

; 2.5/Sin x° = 3/Sin 28°

; 3Sin x° = 2.5Sin 28°

sin x° = (2.5 × sin 28°) / 3

x = arc sin{(2.5 × sin28°) / 3}

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
