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 
, to find the angle you would need to find sin⁻¹ of which is x = sin⁻¹ (0.75). Therefore x equals approximately 49°.
Answer: Width would become 21 and length would become 33. Original perimeter is 100, increased perimeter is 108 which is a 7.69% increase
Write it in a simplest form so you can better understand the sock that are =46
The statement is correct because if you were to take a protractor to each corner, it will measure exactly 90°
8/10 and 48/60 are equivalent because you can see the 48/60 can divide by 8/10 is 6, you just have to see if the larger fraction can divide the smaller one.
