Given :

• Angles of triangle are 45°, 68° and 3x + 16°

To Find :

• Value of x

Solution :

According to question,

➨45° + 68° + 3x + 16° = 180° [ Angle Sum Property of triangle ]

➨ 129° + 3x = 180°

➨ 3x = 180° - 129°

➨ 3x = 51

➨ x = 51/3

➨ x = 17

Additionally :

• Angle Sum Property of triangle is 180°

• Angle Sum Property of quadrilateral is 360°

• Sum of angles in a straight line is 180°

• Linear Pair = 180°

Answer 2

Answer:

x = 17 degree

Step-by-step explanation:

In a triangle , the sum of 3 angles is 180 degree !

45 + 68 +(3x+16) = 180

113 + 3x + 16 = 180

3x + 129 = 180

3x = 180 - 129 = 51

3x = 51

x = 51/3 = 17

THEREFORE x = 17 degree !

I HOPE THIS IS HELPFUL !
