Question

Three angles of a quadrilateral are equal and
the measure of the fourth angle is 120°. Find
the measure of each of the equal angles

Answer 1

Answer:

Here it is......

Let the three angles be 'x'.-

• ATQ,
• 3x+120=360 (sum of all the angles of a quad.)
• 3x=240
• x= 80

Answer 2

Answer:

Step-by-step explanation:

let three angles of a quadrilateral =3x

one angle=120°

sum of angles in a quadrilateral =360°

so,

3x+120°=360°

3x=360°-120°

3x=240°

x=240°/3

x=80°
