Question

please give me right answer​

Answer 1

Answer:

THE ANSWER IS VERY SIMPLE I THINK SO

LIKE THIS

THE SUM OF TWO SIDES OF A TRIANGLES EG- 30 AND 60 SO WHEN WE ADD THEM THE ANSWER COMES 90

THEN THE SUM OF ALL SIDES OF A TRIABGLES IS 180 SO WE WILL SUBTRACT 90 FROM 180 THEN THE ANSWER WILL COME 90

THE ANSWE OF THESE TAE SAME YOU CAN TAKE ANY OTHER EXAMPLE ALSO

BUT IT DOESNT WORK IN ALL SITUATIONS
