Question

three angles of a quadrilateral are 50 degrees, 40 degree and 23 degree full stop find its fourth angle

Answer 1

your answer is here:

sum of all angles of quadrilateral is 360 degree

then sum of given angles will be 113

so if will subtract given angles from sum of all angles we will get our answer

so, 360-113

the fourth angle is 247

hope it will helpful to you!!!!!!!!!

Answer 2

We know that,
50°+40°+23°+fourth angle = 360°
Therefore :- fourth angle= 360°-113°
:- fourth angle= 247°
