Question

three angles of a quadrilateral are 65 ,115 and 60. find the fourth angle

Answer 1

hey buddy !! here's your answer...

all the angles of a quadrilateral add up to give 360°

so, let the unknown angle be x

65 + 115 + 60 + x = 360°
240 + x = 360

hence,
➡️ x= 120°

hope it helps !! ✌️✔️

Answer 2

Hey mate

Here is ur answer by Lavanya Kumari

Explanation :-
Let the fourth angle be x.
We know that sum of all angles of a quadrilateral is 360.
Therefore, 65+115+60+x= 360.
240+x =360
X = 360-240
X = 120.
Hence the fourth angle is 120.
