Answer: yes it is a right angle triangle
Step-by-step explanation:
a^2 + b^2 = c^2
8^2+ 5^2 = ?
64 + 25 = square root of 89
square root of 89 = 9.4
when we round 9.4 it is 9
so
22- (8+5) =
22 - 13 = 9

Step-by-step explanation:
P( two white) = 18/40 * 17/39 = 51/260
P( black then red) = 12/40 * 10/39 = 1/13
P( two black) = 12/40 * 11/39 = 11/130
P( white then black) = 18/40 * 12/39 = 9/65
