WILL GIVE BRAINLIEST!! Redshift is observed when:

3. A distant luminous object travels rapidly towards an observer.

4. A luminous object is traveling alongside an observer.

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

d.) yes, because the volume of the cone is greater than the volume of the sphere
