Triangle XWV is an equilateral triangle(every angle is 60). So both angle V's are vertical angles, which means the are the same(60). Y is 90. So once you have 60 and 90 in triangle YZV, you know the last angle(Z) is 30. But since angle Z is 30 and angle X is 60, they are complementary and not supplementary(which adds up to 180)
2/3+4/9
denominator= 3*9=27
numerator = (18+12)= 30
therefore the answer is 30/27= 10/9
Using PEMDAS, 3x 100,00= 300,000 4x10,000= 40000 8x100=800 3x10=30 add them all together 300,000+40,000+800+30+9 =======34,839
To get a sum of eight the first die must be 2 or greater and the second die must be one specific value that makes the sum equal to 8 with respect to the first die.
So the probability of Donna winning on her next turn, rolling a sum of 8 is:
(5/6)(1/6)=5/36
