Question

if three angles of a quadrilaterial are 100, 105,75,degrees then the measure of the fourth is 110,100,90,80

Answer 1

Answer:

The sum of all angles of a quadrilateral is 360°.

Angle 1 + Angle 2 + Angle 3 +Angle 4 =360°

100+105+75+Angle 4=360°

Angle 4= 360-280= 80°

Ans→ 80°

Answer 2

Answer:

Angle 1 + Angle 2 + Angle 3 + Angle 4 = 360 degree

100+105+75 angle4=360 degree

Angle 4= 360- 280=80 degree
