Answer:
x = 9
Step-by-step explanation:
Rule: the two interior angles F and E when added, equal <FGH.
so
6x + 16 + 60 = 13x + 13 Combine the terms on the left.
6x + 76 = 13x + 13 Subtract 13 from both sides.
6x + 76-13 = 13x Combine
6x + 63 = 13x Subtract 6x from both sides.
63 = 7x Divide by 7
63/7 = x
x = 9
Any sum over 6 or more is likely to be rolled than a sum smaller than 6 because there is more of a probable chance to roll two dice with three or higher compared to rolling three or lower. of course this is theoretical probability, not experimental probablility ( physically rolling dice.)
