Good for them ! They worked with things that are related to math
and arithmetic, they had some fun, and they learned something.
Much better than just fishing for answers on some boring website.

Answer:
81°
Step-by-step explanation:
Points A, B and C lie on the circle. A and C are endpoints, B is the vertex of the angle ABC. Angle ABC is inscribed angle subtended on the arc AC with measure 192°.
The measure of the inscribed angle subtended on the arc is half the measure of the central angle subtended on the same arc. The measure of the central angle is the same as the measure of the arc, so
Answer: After 4.55 hours the ships will be nearest to each other, and this distance would be 54.54 km.
Step-by-step explanation:
Since we have given that
Distance between ship A and ship B = 100 km
Speed at which Ship A is sailing west = 12 km/hr
Speed at which Ship B is sailing south = 10 km/hr
Since they are sailing opposite to each other, so their relative speed would be
So, Time taken is given by
Distance would be
Hence, After 4.55 hours the ships will be nearest to each other, and this distance would be 54.54 km.
Answer:
Step-by-step explanation:
<u><em>The correct question is</em></u>
Find the cosine of ∠A
The picture in the attached figure
we know that
In the right triangle ABC
The cosine of angle A is equal to divide the adjacent side to angle A by the hypotenuse of the right triangle
so
----> by CAH
substitute the given values
