Answer:

A lighthouse is observed by a ship�s office on watch at an angle of 42 degree to the path of the ship.

At the next sighting the lighthouse is observed at an angle of 90 degree to the path of the ship.

The distance travel between sightings is 1800 m .

To the nearest meter, how far away is the ship to the lighthouse at this second sighting?

This situation, forms a right triangle, we can use the tangent of 42 degrees

where

side adjacent = 1800 m

side opposite = distance (d) from the ship to the lighthouse when the angle is 90

tan(42) = d%2F1800

d = .9004 * 1800

d ~ 1621 meters from the ship to the light

Answer:

C) The diagram in this figure illustrates a reflex angle

Step-by-step explanation:

Given : A diagram with an angle.

To find : The diagram in this figure illustrates a _______ angle.

Solution : We can see from figure it is greater than 180 degree and less than 360 degree.

By the definition of reflex angle : The reflex angle is the larger angle. It is more than 180° but less than 360°.

Therefore, C) The diagram in this figure illustrates a reflex angle.
