Answer:
Step-by-step explanation:
Since we are given 2 angles and 1 side, to determine AB, 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.
Therefore
AB/Sin62 = 7.3/Sin70
Cross multiplying, it becomes
AB × Sin 70 = 7.3 × Sin 62
AB × 0.9397 = 14 × 0.8829
0.9397AB = 12.3606
Dividing the left hand side and the right hand side of the equation by 0.9397, it becomes
0.9397AB/0.9397 = 12.3606/0.9397
AB = 13.2 to the nearest tenth
