Answer:
a. 360.323 m
b.
Step-by-step explanation:
Distance covered from A to B = speed x time
= 110 x 2.8
= 308 m
Distance covered from B to C = speed x time
= 110 x 1.7
= 187 m
The sum of angles at B = +
=
a. The distance of the plane from it starting point to C can be determined by applying the cosine rule.
=
+
- 2ac Cos B
Sot hat;
=
+
- 2(187 x 308) Cos
But, Cos = 0
So that,
=
+
= 34969 + 94864
= 129833
b =
= 360.323
The distance from A to C is 360.323 m.
b. Applying the sine rule;
=
=
=
Sin A =
= 0.5190
⇒ A = 0.5190
=
The bearing of the plane from its original location = +
=
