Please help me in solving for x and y

for vertical angles they're equal to each other.

thus,

(7x + 30)° = (11x - 24) °

54 = 4x

x = 13.5°

and

(17y - 4) ° = (5y + 38) °

12y = 42

y = 3.5°

.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
