Question

if x,2x,3x,4x,140and160 are the angle hexagon find the sizes unknown angle​

Answer 1

Step-by-step explanation:

sum of angles of hexagon = 720°

720° = x+2x+3x+4x+140+160

720° = 10x+300

720-300 = 10x

420 = 10x

420/10 = x

42 = x

x= 42

2x = 42×2 = 84

3x = 42×3 = 126

4x = 42×4 = 168

unknown angles = 42,84,126,168

Answer 2

Step-by-step explanation:

sum of hexagon=720°

x+2x+3x+4x+140+160=720

10x+300=720

10x=720-300

10x=420

x=42

2x=84

3x=126

4x=168
