Answer:
total sum of interior angkes of a quadrilateral=360°
first angle =72°
second angle=93°
third angle=107°
fourth angle=x
according to the question
72+93+107+x=360
172+x=360
x=360-172
=188
therefore,fourth angle=188°

Step-by-step explanation:
- Here, 1st angle = 72°
- 2nd angle = 93°
- 3rd angle = 107°
- 4th angle = ?
- Now, we know that sum of angles of quadrilateral = 360°
- So, 72° + 93° + 107° + 4th angle = 360°
272° + 4th angle = 360°
fourth angle = 360° - 272 ° = 88°
