If a quadrilateral has three angles measuring 60',45' and 100' what is the angle of the fourth angle​

Respuesta :

Answer:

155°

Step-by-step explanation:

The sum of the 4 interior angles of a quadrilateral = 360°

Subtract the sum of the 3 given angles from 360 for fourth angle

fourth angle = 360° - (60 + 45 + 100)° = 360° - 205° = 155°
