Answer:
Step-by-step explanation:
Considering the given triangle QED, to determine ED, 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
ED/SinQ = EQ/SinD = QD/SinE
Therefore
ED/Sin 49 = 2/Sin 35
Cross multiplying, it becomes
EDSin35 = 2Sin49
0.574ED = 2 × 0.755
0.574ED = 1.51
ED = 1.51/0.574
ED = 2.63 in
