Question

Two angles of quadrilateral are 140° and 100° if remaining two angles are eqal then the measure each angle eqal to ________​

Answer 1

Answer:

60 degrees

Step-by-step explanation:

sum of all angles of a quad is 360

2 angles are 140 and 100 so the sum of remaining 2 angles will be 120

therefore each angle will be of 60 degree

Answer 2

Step-by-step explanation:

let ABCD be a quadrilateral

GIVEN: two angles in a quadrilateral are 140° and 100°.

let angle A=140°

angle B=100°

GIVEN: Remaining two angles are equal

let angle C= angle D=x

sum of all angles in a quadrilateral=360 °

angle A+angle B+angleC+AngleD= 360°

140°+100°+x+x=360°

240°+2x=360°

2x= 360°-240°

2x=120°

x=120°÷2

x=60°

therefore the measure of each angle is 60°
