Answer: g = 9.8
Step-by-step explanation:
Considering the given triangle EFG, to determine side g, we would apply the sine rule. It is expressed as
a/SinA = b/SinB = c/SinC
Where a, b and c are the length of each side of the triangle and angle A, Angle B and angle C are the corresponding angles of the triangle. Likening it to the given triangle, the expression becomes
e/SinE = f/SinF = g/SinG
Therefore
g/Sin 26 = 22/Sin 81
Cross multiplying, it becomes
gSin81 = 22Sin26
0.988g = 22 × 0.438
0.988g = 9.636
g = 9.636/0.988
g = 9.8
