Question

4. If the three angles of a quadrilateral are 36, 108° and 156. Find the fourth angle​

Answer 1

Answer ⤵️

• Finding the Fourth Angle of a Quadrilateral. The sum of the interior angles of a quadrilateral are equal to 360o. To find the fourth angle of a quadrilateral when the other three angles are known, subtract the number of degrees in the other three angles from 360° .

Answer 2

Always remember sum of angles of any figure including a quadrilateral=360 degrees

so ,take the fourth angle as x

36+108+156+x=360

300+x=360

x=360-300

x=60

Therefore the fourth angle is 60degrees
