Solution:
 
Substitute capital delta theta space equals space 30 space to the power of o
 
In the below relationship,
 
T equals T subscript 0 open parentheses 1 plus fraction numerator alpha capital delta theta over denominator 2 end fraction close parentheses A l s o space p u t space t h e space g i v e n space v a l u e space o f space alpha A n d space f i n d T over T subscript 0
