Answer 1

Answer:

4x + 30 because its an acute and obtuse

Answer 2

Answer:

Angle MON = 130°

Step-by-step explanation:

since, we know ;

m LON = m LOM + m MON

( m LON = 180°, because it forms a straight line, that is " linear pair " )

so,

• =》m LOM + m MON = m LON
• =》4x + 30° + 8x + 90° = 180°
• =》12x + 120° = 180°
• =》12x = 180° - 120°
• =》12x = 60°
• =》x = 60° ÷ 12
• =》x = 5°

x = 5°

now,

=》m MON = 8x + 90°

=》m MON = ( 8 × 5° ) + 90°

=》m MON = 40° + 90°

=》m MON = 130°
