Answer:
In a quadilateral the angles add up to
360
o
Let's call the angles
3
x
,
4
x
,
5
x
and
6
x
Then:
3
x
+
4
x
+
5
x
+
6
x
=
360
→
18
x
=
360
→
x
=
20
Then the angles are
60 o , 80 o 100 o and 120o (because 3 ⋅ 20 =60 etc)
Check:
60 + 80 + 100 + 120 = 360

Answer:
Answer = angle1= 60°
= angle 2= 80°
= angle 3= 100°
= angle 4= 120°
Step-by-step explanation:
let angle be, x
360°=3x+4x+5x+6x
360°=18x
360/18=x
20= x
so, 3x= 3× 20= 60°
4x= 4× 20 = 80 °
5x=5× 20= 100°
6x= 6× 20 = 120°
