Answer:
This shape is a hexagon. Angles in a hexagon add to 720 degrees.
2(y) + 4(2y-20) = 720
2y + 8y-80 = 720
10y-80=720
10y=800
y=80

Answer:
x = 3 & x =- 2
Step-by-step explanation:
|4x - 2| = 10
separate this into 2 equations a positive and a negative
4x-2 =10 and 4x-2 = -10
add 2 to each side
4x-2+2 =10+2 4x-2 +2 = -10 +2
4x =12 4x = -8
divide by 4
4x/4 = 12/4 4x/4 = -8/4
x =3 x=-2
