Question

the two angle of quadrilateral are 60° and 120 degrees and the remaining two angles are equal then find the angle by using formula which type of quadrilateral is​

Answer 1

QUESTION :-

If the two angle of quadrilateral are 60° and 120 degrees and the remaining two angles are equal then find the angles?

SOLUTION :-

Given two angles are 60° and 120°

The other two angles are equal

consider the angles as x

we know that sum of angles in a quadrilateral = 360°

60° + 120° + x° + x° = 360°

180 + 2x = 360

2x = 360 - 180

2x = 180

x = 180/2

x = 90°

Therefore the other two angles are 90° each

Answer 2

Let the equal angles be x

Sum of all angles of a quadrilateral = 360°

60°+120°+x+x= 360°

180°+2x=360°

2x=360°-180°

2x=180°

x=180°÷2

x=90°
