Question

Tolong kerjakan nomor 4 dan 5

Answer 1

Jawaban nomer 4
diagonal = s √2
             = 31 √2


jawaban nomer 5
a = √30² - 24²
   = √900 - 576
   = √324
   = 18 cm
DC = 50 -18
     = 32 cm

Answer 2

No 4
31 = 1/2 a √2
62 = a √2
62/√2 = a

= a

= a

31 √2 = a

diagonal = a = 31√2

jawabnya d

no 5
CD² = AC²-AD²

AC² = AB²-BC²
AC² = 50²-30²
AC² = 2500-900
AC² = 1600

CD² = 1600 - 24²
CD² = 1600 - 576
CD² = 1024
CD = √1024
CD = 32

jawabnya b
