PR+QR=25cm. & PQ=5cm. determine the value of sinP, cosP. Questions-3 Questions-4 Questions-5  sec4A=cosec(A-20) ,if 4A is an acute angle find the value of A. Previous years questions for SSC trigonometry Questions -6 QUESTIONS -7 prove Questions-8&9 Questions-10 Express​ the Trigonometry ration sinA, secA, tanA in terms of CotA.
