Question

Solve :



2) One angle of a quadrilateral is 180° and the remaining three angles are equal.

Find the three equal angles.​

Answer 1

Answer:

60°

Step-by-step explanation:

because the sum of 4 angles of quadrilateral is 360°. if one angle is 180° then sum of other three angle is 180°. 180/3= 60°

Answer 2

Answer:

60°

Step-by-step explanation:

Given -

One quadrilateral having an angle of 180°, remaining three angles are equal.

To find -

Remaining three angles

Solution -

Let us think remaining angle as x, so two more angles will be x. because all are equal.

Sum of all angles of quadrilateral = 360°

=> x + x + x + 180° = 360°

=> 3x + 180° = 360°

=> 3x = 360° - 180°

=> 3x = 180°

=> x = 180° ÷ 3

=> x = 60°

Hence remaining three equal angles will be 60° each.

hope it helps.
