An angle is defined as the figure, in which two rays meet at a common point called the vertex.
Angles are formed when two lines intersect at a point. The measure of the 'opening' between these two rays is called an 'angle'. It is represented by the symbol ∠. Angles are usually measured in degrees and radians, which is a measure of circularity or rotation. In geometry, an angle is formed when two rays are joined at their endpoints. These rays are called the sides or arms of the angle. Let us read about the different parts of an angle.
There are two main parts related to an angle - the arms and the vertex. Vertex is a common endpoint that is shared by the two rays. Observe the figure in which the vertex O is marked as the joining point of the two arms.
An angle is measured in degrees. One full rotation around a point forms a complete angle of 360°.

Answer: 18:1
Step-by-step explanation:
450 students : 25 teachers
18 students : 1 teachers
450/25= 18
Answer:
D. 18 : 1
Step-by-step explanation:
Students : teachers and aides
450 : 25
Treat it like a fraction. 450 over 25 simplifies to 18 over 1 because 450/25=18 and 25/25=1.
Therefore, the ratio is 18 : 1

Answer:
Step-by-step explanation:
sin x=−4/5
x=sin^-1(4/5)
x=about 53.1
x=(-4/5)/sin(53.1 degrees)=about -2.64662408617
