Penyelesaian
Besar CBD pada gambar dibawah ini adalah 110°
- 180 - ( ABD + DBC
- 180 - (5x + (3x + 4)
- 180 - 8x + 4
- 8x = 180 - 4
- 8x = 176°
- x = 176 ÷ 8
- x = 22°
Besar CBD
- CBD = 5x
- CBD = 5(22)
- CBD = ( 5 x 22 )
- CBD = ( 5 x 20 ) + ( 5 x 2 )
- CBD = 100 + 10
- CBD = [tex]{{ \boxed{{{\sf {{\red{{ 110° }}}}}}}}}[/tex]
[tex] \\ [/tex]
<ABD + <DBC = 180
5x + (3x + 4) = 180
5x + 3x + 4 = 180
8x + 4 = 180
8x = 180 - 4
8x = 176
x = 176/8
x = 22
-
<CBD = 5x⁰
<CBD = 5(22)⁰
<CBD = 110⁰ (B)
