Question

plese.. tell answer i requier☹

Answer 1

HEY....



NOTE : IN A QUARDILATERAL.. THE SUM OF ALL ANGLES IS 360°....



SO... LET THE ANGLE BE x....

$3x + 4x + 5x + 6x = 360$


$18x = 360$


$x = \frac{360}{18}$


$x = 20$


IF... x = 20...

3x is 60 ....
4x is 80....
5x is 100...
6x is 120...

Answer 2

$\ Step\ by\ step\ explanation$

Let the angle of quadrilateral be 3x, 4x, 5x, 6x

we know that

sum of all angles of a quadrilateral = 360 degree

according to question

3x+4x+5x+6x = 360

18x = 360

x= 20

Hence, the angles are

3x = 3*20 = 60 degree

4x = 4*20 = 80 degree

5x = 5*20 = 100 degree

6x = 6*20 = 120 degree
