Question

two angle of a quadrilateral are of measure 70 degree each the other two angles are also equal what is the
measure of either of these two angles

Answer 1

We know that sum of the angle of a quadrilateral is equal to 360∘360∘Given :Three angles are equalLet the equal angle be x3x+120=3603x+120=3603x=2403x=240x=2403x=2403=80=80Hence the three angles are 80∘80∘Answer : 80

Answer 2

Angle sum property of a quad is 360°
Since the remaining two angles r equal
Therefore let it be x
Then,
70+70+x+x=360
140+2x=360
X=360-140/2
X=220/2
X =110
Thus, the remaining two angles r 110°each..
