tolong dijawab ya pake cara pliss

31) 150 + 75 + x + 200 + 175 = 725
                                    x+600 = 725
                                           x  = 125 ton (A)
32) hsl panen slruhnya = 600 kwintal (360 ^{0})
      derajat mangga      = 360 ^{0} -(36^{0}+126^{0}+90^{0})
                                     = 108 ^{0}
     panen mangga =[tex] \frac{108 ^{0} }{360 ^{0} } [/tex] x600
                              = 180 kwintal (D)
