Question

the three angles of a quadilateral are equal and fourth angle is 120°. find the three angles.

Answer 1

Hey there
let a b c d be the angle of quadrilateral

a + b + c + d = 360 ( Angle sum property)
3a + 120 = 360
3a = 240
a = 80

Hence the angles measures are 80 , 80 , 80 , 120

hope this helps u

Answer 2

Let The 3 Angle be x

x+x+x+120° = 360°
(Angle Sum Property Of A Quadrilateral)

3x + 120° = 360°
3x = 360° - 120°
3x = 240°
x = 240/3
x = 80°

Ans)- The Three Angles Are Of 80°
