Question

samantha points a telescope at an altitude of 32° to see the star pollux. then she lowers the telescope to an altitude of 25° to see a planetary nebula. answer 2 questions about the telescope. 1. what was the change in telescope angle from pollux to the planetary nebula? 2. how many degrees apart were pollux and the planetary nebula?

Explanation:

Step1: Calculate change in angle

To find the change in the telescope angle, we subtract the final angle from the initial angle. The initial angle (to see Pollux) is $32^{\circ}$ and the final angle (to see the planetary nebula) is $25^{\circ}$. So the change is $32 - 25$.
$32-25 = 7$

Step2: Answer the second - part

The number of degrees apart between Pollux and the planetary nebula is the same as the change in the telescope angle. So it is also $7^{\circ}$.

Answer:

1. $7$
2. $7$
