Question

three angles of quadrilateral 50 degrees 40 degrees 123 degrees find fourth angle ​

Answer 1

Answer:

Three angles of Quadrilateral are:- 50°, 40°, 123°.

We know that the sum of all the interior angles of a Quadrilateral is 360°.

So, Let the angle be x, so that

x + 123° + 40° + 50° = 360°

or, x = 360° - ( 123° + 40° + 50° )

or, x = 360° - 213°

or, x = 147°.

So, the fourth angle is 147°.
