An astronomer knows the distances from herself to stars A and B as well as the distance between them.
The distances are 450, 400, and 90 light years (1.y.) respectively.
If the astronomer's telescope is currently pointed at star A. how many degrees must she rotate her
telescope to see star B?
Do not round during your calculations. Round your final answer to the nearest degree,
B
90
400 l. y.
Astronomer
450 l. y.

what does muffins have to do with anything?

step-by-step explanation:

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
