Answer:
7/25 Hope it helps
Explanation:
Given sin theta = 7/25;
Cosec of any variable is the reciprocal of sin of the variable. Therefore cosec theta = 1/sin theta
Substituting the value of sim theta given in the formula for cosec theta gives;
Cosec theta = 1/(7/25)
Cosec theta = 1÷7/25
Cosec theta = 1× 25/7
Cosec theta = 25/7
