Kuis tengah malam guys...

1.sudut sudut di dalam lingkaran.

( 2x + 3 ) + 75 = 180

2x + 3 + 75 = 180

2x = 180 - 3 - 75

2x = 102

x = 102/2

x = 51

140 + ( 3y - 5 ) = 180

140 + 3y - 5 = 180

3y = 180 + 5 - 140

3y = 45

y = 15

nilai dari ;

x - 2y = 51 - 2 ( 15 )

. = 51 - 30

. = 21

opsi pilihan ( b )

2.Sudut AOD = 180° - sudut AOB

Sudut AOD = 180° - 50°

Sudut AOD = 130°

Sudut ACD = 1/2 . sudut AOD

Sudut ACD = 1/2 . 130°

Sudut ACD = 65°
