Question

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

Answer 1

let the measures of the three angles be a, b ,c and that of 4th be d.
then a+b+c+d = 360
5d + d = 360
6d = 360
d = 60° ans.

Answer 2

Bonjour !!!!❤❤❤

Here is your answer
_________________________________________________________

Let the fourth angle be x

Sum of three angles = 5x

We know ,

Sum of all angles of a quadrilateral is 360°


x + 5x = 360

6x = 360

x = 360/6

x = 60°

Ans :

The fourth angle measures 60°.
