Step-by-step explanation:
Answer:
(1). 450 degree and 90 degree.
(2). - 270 degree and - 990 degree.
Step-by-step explanation:
So, we are given the the following data or parameters in this question or problem; A = -630 degree, and we are to look for the next two positive and two negative angles that are coterminal with the given quadrantal angle.
For the positive(+ve) angles we have that;
- 630 degree + 1080 degree = 450 degree; and - 630 degree + 720 degree= 90 degree.
For the negative(-ve) angles we have that;
- 630 degree + 360 degree= - 270 degree and - 630 degree - 360 degree = - 990 degree.
Answer: then he had $70.80

Answer:
A circle is a shape.
Step-by-step explanation:
In geometry circles are known for you to solve the radius wit the formula A= π r^2
A circle is a shape consisting of all points in a plane that are a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant.
