(1) The ratio of measure of 4 angles of a quadrilateral are 3:4:5:6, find all angles.​

Answer 1

Answer:

Step-by-step explanation:

we know sum of quadrilateral is 360

Let be 3x, 4x, 5x, 6x

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

18x=360

X=360/18

X=20

3x=20*3=60

4x=20*4=80

5x=20*5=100

6x=20*6=120

we know sum of quadrilateral is 360°

Let be 3 x, 4x, 5x, 6 x

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

18 x = 360

x =360 /18

x =20
