Question

tolong di jawab kak!​

Answer 1

Penjelasan dengan langkah-langkah:

KOM + MOP + POL = 180° (sudut lurus)

( 3X + 11 ) + 90° + ( 6X - 2 ) = 180°

9X + 9 = 90°

9X = 81°

X = 9°

maka :

KOM = 3X + 11 = 3(9) + 11 = 38 °

POL = 6X - 2 = 6(9) - 2 = 52°

ditanya :

A ) LON → MOP + POL + LON = 180°

90° + 52° + LON = 180°

LON = 38°

B ) sudut pelurus POL = 180° - 52°

= 128°

semoga membantu :)
