Iwould very much appreciate
explain how you use a straightedge and a compass to construct an angle that is both congruent and adjacent to a given angle.

An adjacent angle is one of two angles that lie next to each other. They both share a common boundary line but do not overlap each other.  Congruent angles are angles that are opposite each other. They  only share a center point. You construct an adjacent angle and a congruent angle using a straight line and a compass by drawing two congruent angles with the same size angle in both angles. Because both angles are constructed using the same compass measurement; both angles are considered to be both congruent and adjacent. 

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw
