In a part of the universe there is a star that has four planets. the first planet has an orbit of 6 earth years. the second planet has an orbit of 15 earth years. the third planet has an orbit of 8 years and the fourth planet has an orbit of 10 earth years. if they were in conjunction this year, how long will it be until they are in conjunction again?

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.
