Question

In A Quadrilateral One Angle Is 120° And Three Remining  Angles Are Equal. Find The Angle Measure Of Each Of The Equal Angles.​

Answer 1

Answer:

GIVEN -

• A quadrilateral
• one angle is 120°
• other 3 angles are equal

TO FIND -

• Measure of each angles

SOLUTION -

Given, 3 angles are equal

Let the 3 angles be 3x

We know that sum of all angles of a quadrilateral = 360°

120 + 3x = 360

3x = 360 - 120

3x = 240

x= 240/3

x= 80 °

Measures of all angles = 80° , 80°, 80° , 120°
