CscA = 1/sinA
CosACscA = cosA × 1/sinA = cosA/SinA = cotA
This is a conversion problem. We know that 1 mile is 5280 feet, right? Since Ellie lives 2 miles, and two is double of 1, we just take 5280 and multiply that by two (or add it twice) to find how many feet is between Ellie's house and school. 5280 x 2 = 10560 (you get the same answer if you add 5280 twice). Therefore, 10560 feet lies between Ellie's house and school.
Answer:
An angle can be named in different ways:
•by a number or letter written inside the angle.
•by the name of the vertex.
•by the vertex and a point on each ray.
Answer:- Option A "ray" is the right term which matches with the definition.
Explanation:-
A ray is a line that has one fixed endpoint, and extends infinitely along the line from the fixed endpoint.
Therefore, the term which matches with the given definition is "ray".
Thus A linear set of points with a unique starting point and extending infinitely in one direction is called a ray.
Answer:
1/2
Step-by-step explanation:
1/4=2/8
2/8+2/8=4/8=1/2
