Question

three angles of a quadrilateral are 100,90and110 what is the fourth angle? ​

Answer 1

Answer:

sum of quad. is360

100+110+90+x=360

300+x =360

x=360-300=60

Answer 2

Answer:

we know that,

sum of four angles of a quadrilateral= 360°

three angles are = 100°, 90°, 110°

let fourth angle be x°

therefore,

=> 100° + 90° + 110° + x°= 360°

=> 300° + x°= 360°

=> x° = 360° - 300°

=> x° = 60°
