question: What is the total sum of Areas (sq.deg) that have an Area (msr) of 43.059 and a Right ascension (hm) larger than 747.73?
answer: SELECT SUM(area__sqdeg_) FROM table_name_47 WHERE area__msr_ = 43.059 AND right_ascension__hm_ > 747.73
context: CREATE TABLE table_name_47 (area__sqdeg_ INTEGER, area__msr_ VARCHAR, right_ascension__hm_ VARCHAR)
