Explain the difference between using the sine ratio to solve for a missing angle in a right triangle versus using the cosecant r
oksano4ka [1.4K]

Answer:

The sine ratio is the ratio between the opposite side over hypotenuse. The cosecant ratio is the ratio between the hypotenuse over the opposite side, therefore cosecant is the reciprocal of sine.

To find a missing angle using sine, you would need to use the inverse of sine. For example,  if the sine was  \frac{30}{40}, to find the angle you would need to find sin⁻¹ of  \frac{30}{40} which is x =  sin⁻¹ (0.75). Therefore x equals approximately 49°.

Grace [21]

8 x 5 = 32 is the expression. Since Sergei caught 4 striped fish that all weigh the same, we know that we can multiple the weight of one fish by the amount of fish he caught.

Since he also caught another fish that would make the total of fish 5.
