180 = 5x + 17 + 5x - 27
180 = 10x - 10
10x = 180 + 10
10x = 190
x = 190 ÷ 10
x = 19
< CED = 5x + 17
< CED = 5(19) + 17
< CED = 95 + 17
< CED = 112° (D)
90 = 6x + 3x
90 = 9x
x = 90 ÷ 9
x = 10
Sudut CBD = 3x
Sudut CBD = 3 × 10
Sudut CBD = 30° (C)
16.) Tentukan nilai x
Sekarang mencari Besar sudut CED
17.) Tentukan nilai x
Sekarang Besar penyiku sudut DBE
