A fish is 12 meters below the surface of the ocean. What is its elevation? A sea bird is 28 meters above the surface of the ocean. What is its elevation?
If the bird is directly above the fish, how far apart are they?

The answer to the first question is -12. The answer to the second question is 28. The answer to the third question is 16 meters apart.

Step-by-step explanation:

If the fish is 12 meters below sea level, its elevation is -12. If the sea bird is 28 meters above sea level, its elevation is 28. If the bird is directly above the fish, they are 16 meters apart because if you subtract 12 from 28 you get 16. I hope this helps you, have a wonderful day! :D

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
