Question

1. If three angles of a quadrilateral are 75°, 90° and
950, find the remaining angle.​

Answer 1

Step-by-step explanation:

Total sum of angles in a quadrilateral = 360°

Let x be the remaining angle.

75°+90°+95°+x = 360°

260°+x = 360°

x = 360°-260°

therefore, X = 100°

Answer 2

Answer : 100 degree

Step by step Explanation :

Sum of angles of a quadrilateral is 360 degrees

Let the remaining angle be x.

Then,

75 + 90 + 95 + x = 360

75 + 185 + x = 360

260 + x = 360

x = 360 - 260

x = 100

Hence, the remaining angle is 100 degree
