Question

2 angle of quadrilateral are equal are equal and third and fourth angles are equal to 60°and 120°,find the equal angles​

Answer 1

Let each of the equal angles be = x

Sum of angles of a quadrilateral is 360°.

So, 2x + 60° + 120° = 360°

i.e. 2x = 180°

x = 90°

Answer 2

Answer:

Step-by-step explanation:

Sum of the angles of a quadrilateral=360

Let the equal angles be=x

So,

x+x+60+120=360

2x+180=360

2x=360-180

X=180/2

x=90

Therefore the other two equal angles are 90 degree
