Question

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

Answer 1

Answer:

Step-by-step explanation:

Given :-

The sum of three angles of a quadrileteral is 5 times the fourth angle.

To Find :-

The Fourth Angle

Solution :-

Let the fourth angle be x

Sum of three angles = 5x

According to the Question,

Sum of all angles of a quadrilateral = 360°

⇒  x + 5x = 360

⇒  6x = 360

⇒ x = 360/6

⇒ x = 60°

Hence, The fourth angle measures 60°.
