1 votes 1 votes Option C is Correct. Draw Acute angle Triangle and plot tan theta value as perpendicular / base i.e 8/15 Calculate hypotenuse using pythagorean theorem and hypotenuse comes out to be 17. so cosec is =1/sine theta = hypotenuse / perpendicular =17/8 Shubham Sharma 2 answered Mar 10, 2017 Shubham Sharma 2 comment Share Follow See all 0 reply Please log in or register to add a comment.
