Question

1 How many sides a regular polygon has, whose each exterior angle is 45°?*
a 6
b 5
c 8
d 10
2. The 4 angles of a quadrilateral are in the ratio 1:2:3:4, then the smallest 1 point
angle is
a20°
b18°
c120°
d 360​

Answer 1

Answer:

1) c .8

2) d. 36

Step-by-step explanation:

2. let's angle of quadrilateral be x, 2x, 3x, 4x

x+2x+3x+4x=360 (sum of all angles of quadrilateral)

10x=360

x=360/10

x=36 smallest angle
