Question

Three angles of a quadrilarel are 100 , 60, 110 ,find its fourth angle

Answer 1

Answer: sum of all four angle of quadilateral =360

lets take fourth angle =x

100+110+60+x=360

270+x=360

x=90

Step-by-step explanation:

Answer 2

Hey mate !!!

Answer :-

The 3 angles are ..100° ,60°,110°,

let the fourth angle be x

sum of angles in quadrilateral = 360°

Now ,

=> 100 + 60+110+x = 360

=>270 + x = 360

=> x = 360-270

=> x = 90°

Hence ,fourth angle is 90°
