Question

Find the value of x in the following​

Answer 1

Answer:

50

Step-by-step explanation:

Therefore,

  x + 10 + x + 20 + X = 180 ( Supplimentary Angles )

= 3x + 30                   = 180

= 3x                           = 180 - 30

= x                             = 150/3 = 50

Answer 2

Answer:

According to the question ,

• ( x + 10°) + ( x + 20°) + x = 180°
• x + 10° + x + 20° + x = 180°
• 3x + 30° = 180°
• 3x = 180° - 30°
• x = 150° / 3
• x = 50°

therefore , the angles are

60° , 70° and 50°

respectively
