Bantu jawab pr saya dong!!
pr saya no 4!!
beri cara kerja yah!!!

Answer 1

< SRQ = 21°
< SPR = 27°

< PRS = < SRQ = 21°

< SQR = < SPR = 27°

< PRQ = < SRQ + < PRS
           = 21° + 21°
           = 42°

sudut pusat = 2 x sudut keliling
< PSQ = 2 x < PRQ
           = 2 x 42°
           = 84°

semoga membantu ya :)
