Answer 1

Penjelasan dengan langkah-langkah:

5.a

[tex]3x + x - 20 = 180 \\ 4x - 20 = 180 \\ 4x = 180 + 20 \\ x = \frac{200}{4} = 50[/tex]

b.

[tex] < abd = 3x = 3(50) = 150 [/tex]

c.

[tex] < dbc = x - 2 = 50 - 2 = 48[/tex]

6.a

[tex] < e = 110 \\ < f = 180 - 110 = 70 \\ < g = < f = 70[/tex]

b. luar berseberangan : <A=<H, <B=<G

c. sehadap : <A=<E, <B=<F, <C=<G, <D=<H
