N
A coastguard sees a boat on a bearing of 038° from
him and 25 km away. He also sees a ship 42 km away
and on a bearing of 080°. Calculate:
a) the distance of the boat from the ship
b) the bearing of the boat from the ship.
Ship

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

d
