siapa yg bisa jawab semuanya tak jadiin yg terbaik oke ;)


32. 2x = 72 –> x = 36, 3y = 180 – 72 – (2.36), 3y = 180 – 72 – 72, 3y = 36, y = 12, jadi x + y = 36 + 12 = 48 .., mohon koreksinya jika km kurang yakin :),

32. Karena itu adalha segitiga sama kaki otomatis sudut B dan C sama jadi, 2x = 72, x = 72 : 2 = 36, 72 + 72 + 3y = 180, 144 + 3y = 180, 3y = 180 – 144, 3y = 36, y = 12, x + y = 36 + 12 = 48, 33. 2x + ( 3x – 5 ) + ( 4x + 14 ) = 180, ( 2x + 3x + 4x ) + ( -5 + 14 ) = 180, 9x + 9 = 180, 9x = 180 – 9, 9x = 171, x = 19, BESAR SUDUT, 2x = 2 \xd7 19 = 38, 3x – 5 = 3 \xd7 19 – 5 = 52, 4x + 14 = 4 \xd7 19 + 14 = 90, 34. QSR = 180 – ( 25 + 25 ), = 130, PSQ = 180 – 130 , = 150, PQS = 180 – ( 50 + 50 ), = 80, PQR = PQS + SQR, = 80 + 25, = 105, :),
