Step-by-step explanation:
Case 1 :


Case 2 :


4 Aces, 4 2's, 4 3's 4 4's
= 16 cards total out of 52 cards
so probability would be 16/52 which reduces to 4/13
Answer:
They are not congruent
Step-by-step explanation:
In order to be congruent their angles have to be the same and angle A (60º) and D (40º) are different
1. 4x= 3(18-3x) - 2
4x=54-9x-2
4x+9x=52
13x=52
x=4
substitute 4 for x
4(4)=3y-2
16=3y-2
16 + 2 = 3y
y=6
So your x would be 4 and y would be 6
to check your solution substitute x and y
4(4)=3(6) - 2
16 = 16
Therefore that's the final answer for number 1.
