Question

27. The sum of three angles of a quadrilateral is 5 times the fourth angle. Find the fourth angle. *​

Answer 1

${\tt{\red{\underline{\underline{\huge{✿Solution✿ }}}}}}$

Let 'x' , 'y' , 'z' & 'a' be 1st , 2nd , 3 rd & 4th angle respectively.

So, x + y + z = 5a

Sum of all angles of a quadrilateral = 360°

x + y + z + a = 360°

5a + a = 360°

6a = 360°

a =360 / 6

a = 60°

Therefore, 4th angle is 60°. (Answer).
