Question

Three angles of a qudrilateral are equal . The fourth angle is 120 degree. find the measure of the equal angles.





​

Answer 1

Answer:

80°

Step-by-step explanation:

Given Problem:

Three angles of a qudrilateral are equal . The fourth angle is 120° find the measure of the equal angles.

Solution:

To Find:

The measure of the equal angles.  

----------------------

First of all we know that,sum of the angle of a quadrilateral is equal to "360°"

According to your question:

Given that:

⇒Three angles are equal

⇒Let the equal angle be x

⇒3x+120=360

⇒3x=240

⇒x=2403

⇒=80°

Hence the three angles are 80°
