Answer 1

Given iss S = 13 5 - adjacent bypotenuse 13 169-25 x 12 sins = opposite hipotenue 13 given. s is in Quadeant TV in Quadrant TV sine is negative - Sins : -12. 13 tans = 5 opposite adjacent quadrant IV, tangent In is negative tans = -- 1 2 3 5 Given sint als opposite hyutenuse 6 x 25 26 = x² x=3

H cost = 5 3 adjacent hypotenuse is in Quadeant in is positive Given t quadsant, corine cist = 3 H tant = opposite adjacent In 4th quad sant, tangent is negative tant = - 4 a) sin(stt) = sins cost + cosseint (49)(3)+500) -26 - 36-20 Therefore, sin (s+t) -56 65 tan (Stt) tans+ tant 1- tonstant -12 - 4 -36-20 15-48 -(*)05) -56 - 33 33 Therefore, tan(s+t) = 56 33 gine 4th quadrant, ملم s and t both lie in Stt lie in 4th quadrant only. Therefore, lie in ſquadrant IV Stt
