Answer:
hello your question has a missing diagram attached below is the missing diagram
answer :
Mark the point of intersection S of circles R and P, and construct line QS ( option 2 )
Step-by-step explanation:
when constructing a tangent line from one point ( lets say Q as seen in the question ) to a circle P. The next step should be to mark a point of intersection between the given circles and then construct a line through it
Cross multiplying:-
cot^2 x = (csc x+ 1)(csc x + 1)
also cot^2 x = csc^2 x - 1 = (csc x + 1)(csc x - 1) (Known Identitiy)
so the equation is not an identity
