I think it's 60%, I could be wrong
Hope I Helped! Have a nice night!
Angles RZT, RZS, and TZS form triangle RZT, so they sum to 180. Thus, we have:
110+3s+8s=180
Simplifying, we have:
11s=70
Dividing by 11, we see that:
s=70/11
Therefore, RZS=3s=210/11, and TZS=8s=560/11.
S(10) = a + (n-1)d
34 = a + 9d ---- Eqn 1
Sum(20) = n/2(2a +(n-1)d)
710 = 20/2(2a + 19d) ----- Eqn 2
Solve these two equations and find the value of a and d and put the values in the first eqn (a + (n-1)d) to find the 25th term
*n = the term
*a = the starting number
*d = the difference in the series for each number
