Answer:
if ∠1 = 34°
then:
∠2 = 180 - 34 = 146° because it is supplementary to ∠1 (supplementary angles total 180°)
∠3 = 146° because it is a vertical angle of ∠2
∠4 = 34° because it is a vertical angle of ∠1

The recursive function
Let the nth term of the sequence be 
The given sequence is an arithmetic sequence that has the following common difference (d)



So, the nth term is:

Hence, the recursion is:
where 
The probability is 50% because you only rolled twice
