Answer 1

Correct Question :

If sum of two angles of a quadrilateral is 180° , then what is the sum of the Remaining two angles of the quadrilateral.

Given :

⬤ Sum of two Angles of Quadrilateral is 180° .

To Find :

⬤ Sum of Ramaining two angles of Quadrilateral.

Solution :

Let :

• Measure of Remaining two Angles of Quadrilateral be x .

As we know that , Sum of all Angles of Quadrilateral is 360 degree . Hence ,

$\sf{180+x=360^{\circ}}$

x = 360 - 180

x = 180

Therefore , The Value of x is 180°

Hence , Measure of Remaining two angles of Quadrilateral (x) is 180° .

Check :

180 + x = 360

180 + 180 = 360

360° = 360°

Hence Checked .
