Question

Tolong bantuin yang 4 ini yaaa pliss banget pakai cara
bantu dpt pahala amin

Answer 1

6. L = 1/2 X(s1 + s2) X t
       = 1/2 X (12 + 15) X 4
       = 54cm²

1. L = 1/2 X (s1+s2)X t
      = 1/2 X (6+26) X 8
       = 128cm²

24. Sudut BCD = 180 - 75 
                      = 105 derajat

28. 180 - (130+15)
     = 180 - 145
     = 35 derajat

Answer 2

6 ). Luas trapesium = jjs /2 x t t = √5²- 3² = √25- 9 = √ 16 = 4cm L .= 15 + 12 /2 x 4 ..... = 27/2 x 4 ... = 54 cm².. 24 ). 70° +70° + x + x = 360° .. 140° + 2x = 360°... 2x = 360° - 140°.... 2x = 220°..... x = 110° , jadi besar sudut BCD = 110° 28 ) 130° + 15 + x = 180 145° +x = 180 ..... x = 180 - 145 = 35°... 35 + 15 = 50° ....50° - 35° = 15° kadi sudut rpq = 15°
