Question

If three angles of a quadrilateral are each equal to 75°, the fourth angle is ? ​

Answer 1

Answer:

The answer is 135°

Step-by-step explanation:

Let the Fourth angle be X

and we know the the sum of all angles in quadrilateral is 360°

According to Question

If three angles are equal means

75, 75 , 75 respectively then

75 + 75 + 75 + X = 360

225 + X = 360

X = 360-225

X = 135

So, the fourth angle is 135°
