Question

if one angle of a quadrilateral is a 180-degree and the remaining three angles are equal find the each of the three angles​

Answer 1

Answer:

since the remaining three angles are equal, therefore all are 60° each.

Answer 2

Thus as the remaining angles are equal is 60°

Step-by-step explanation:

let the angle be x.

as per question.

x + x + x + 180° = 360°

3x + 180° = 360°

3x = 360°- 180°

x = 180°/3

x = 60°
