For a curved mirror, all points have the same normal and the angle of incidence is also equal to the angle of reflection.
According to the laws of reflection, the incident ray, reflected ray and normal all lie on the same plane. For a curved mirror, the normal remains the same at all points along the curved mirror.
Again, the angle made between the incident ray and the normal is the same as the angle made between the reflected ray and the normal. Therefore, the angle of reflection is equal to the angle of incidence.

Answer:
Astronomers have divided the eight planets of our solar system into the inner planets and the outer planets. The 4 inner planets are the closest to the Sun, and the outer planets are the other four – Jupiter, Saturn, Uranus, and Neptune. The outer planets are also called the Jovian planets or gas giants.

Explanation:
Good morning.
We have:
![\mathsf{\overset{\to}{a} = 29\overset{\to}{j}}](https://tex.z-dn.net/?f=%5Cmathsf%7B%5Coverset%7B%5Cto%7D%7Ba%7D%20%3D%2029%5Coverset%7B%5Cto%7D%7Bj%7D%7D)
Where
j is the unitary vector in the direction of the
y-axis.
We have that
![\mathsf{\overset{\to}{a}+\overset{\to}{b} = -18\overset{\to}{j}}](https://tex.z-dn.net/?f=%5Cmathsf%7B%5Coverset%7B%5Cto%7D%7Ba%7D%2B%5Coverset%7B%5Cto%7D%7Bb%7D%20%3D%20-18%5Coverset%7B%5Cto%7D%7Bj%7D%7D)
We add the vector
-a to both sides:
![\mathsf{\overset{\to}{b} = -18\overset{\to}{j} -\overset{\to}{a} = -18\overset{\to}{j} -29\overset{\to}{j}}\\ \\ \mathsf{\overset{\to}{b}=-47\overset{\to}{j}}](https://tex.z-dn.net/?f=%5Cmathsf%7B%5Coverset%7B%5Cto%7D%7Bb%7D%20%3D%20-18%5Coverset%7B%5Cto%7D%7Bj%7D%20-%5Coverset%7B%5Cto%7D%7Ba%7D%20%3D%20-18%5Coverset%7B%5Cto%7D%7Bj%7D%20-29%5Coverset%7B%5Cto%7D%7Bj%7D%7D%5C%5C%20%5C%5C%20%5Cmathsf%7B%5Coverset%7B%5Cto%7D%7Bb%7D%3D-47%5Coverset%7B%5Cto%7D%7Bj%7D%7D)
Therefore, the magnitude of
b is
47 units.
