Question

the sum of three angles of a quadrilateral is 5 times the fourth angle. find the fourth angle​

Answer 1

Step-by-step explanation:

lets say fourth angle = x

three angles = 5x

so sum of all angles = 6x

summ of all angles in quadrilateral = 360

so 6x = 360

x = 360/6

x = 60

fourth angle = 60
