Question

one angle of a quatilateral neasure 120 degree and rest three angle are of equals measure .find the degree measure of each angle

koi h zinda yha pr​

Answer 1

Let all three equal angles be x

so,

120 + x + x + x = 360

120 + 3x = 360

3x = 240

x = 80°

the measure of each equal angle is 80°

Answer 2

Answer:

• 80° is the measure of each all three angles.

Step-by-step explanation:

According to the Question

It is given that,

• Measure of one angle is 120°
• Rest all three angles are equal

we have to calculate the measure of each angle

Let the rest all equal angles be x

As we know that Sum of all angles in a quadrilateral is 360°

• Sum of all angles = 360°

On substituting the value we get

↠ 120° + x + x + x = 360°

↠ 120° + 3x = 360°

↠ 3x = 360° - 120°

↠ 3x = 240°

↠ x = 240°/3

↠ x = 80°

• Hence, the rest all three angles are 80° .
