Answer 1

Answer:

80°

Step-by-step explanation:

Given:

Two angles of quadrilateral are 80° and 120°, the other angles are equal

To find:

Other angles

Assumption:

Let the other angle be x

Solution:

As , sum of all angles of quadrilateral are 360°

=> 80° + 120° + x + x = 360°

=> 200° + 2x = 360°

=> 2x = 360° - 200°

=> 2x = 160°

=> x = 160°/2

=> x = 80°
