Question

Three angle of a quadrilater are 75°, 90°and 75° then the other angle is ​

Answer 1

Answer :-

• Let the unknown angle be ' x '

So,

75° + 90 ° + 75° + x = 360°

( Sum of angles of a Quadrilateral )

240° + x = 360°

x = 360° - 240°

x = 120°

Final Answer: Other angle is '120°'

Hope it helps you ☺️☺️..!!!

Step-by-step explanation:

We know that the sum of angles in a quadrilateral is 360 degree

so,

talking the fourth angle as x

We get,

75+75+90+x=360

240+x=360

x=120

So the fourth angle is 120 degrees
