In the given figure, O is the centre of the circle PS = SO = PQ/2 and PM = MO, then find the difference between the measures of ∠QRS and ∠PQR.​

Answer»

O is the centre of the CIRCLE PS = SO = PQ/2 and PM = MOTO Find : difference between the measures of ∠QRS and ∠PQR.Solution:PQ is Diameter as it passes through CENTER O=> PO  = RADIUS = Diameter/2  =  PQ/2 PS = SO = PQ/2   Given =>  PS = SO  = PO=> ∠POS = 60° ∠POS +  ∠QOS = 180°  Linear PAIR=> 60° +  ∠QOS = 180° =>   ∠QOS = 120°∠QRS  = (1/2)  ∠QOS => ∠QRS  = (1/2) 120°=> ∠QRS  =60°in ΔPMS  & ΔOMSPM = OM   givenMS = MS   commonPS = SO   given => ΔPMS  ≅ ΔOMS=> ∠PMS  = ∠OMS ∠PMS  + ∠OMS = 180°=> ∠PMS  = ∠OMS = 90° ∠PMS = ∠RMQ  ( vertically opposite angles)=>  ∠RMQ = 90° in   Δ QMR∠RMQ  + ∠QRM  + ∠MQR = 180°​∠QRM = ∠QRS  =60°∠MQR  = ∠PQR=> 90°  + 60° +  ∠PQR = 180°​=> ∠PQR = 30°​difference between the measures of ∠QRS and ∠PQR.​   = 60° - 30°​ = 30°​Learn More:difference between the measures of ∠QRS and ∠PQR.​brainly.in/question/27331116brainly.in/question/27356073
