Answer:

Step-by-step explanation:

x = 180 - 72 = 108° (linear pair)

y = 72° (vertically opposite angles)

z = 180 - (90+72) = 180 - 162 = 18°

Solve for x. 3x ^2 -4 = 8

LenKa [72]

Answer:

x = ±2

Step-by-step explanation:

3x ^2 -4 = 8

Add 4 to each side

3x ^2 -4+4 = 8+4

3x^2 =12

Divide each side by 3

3x^2 =12

3x^2/3 = 12/3

x^2 = 4

Take the square root of each side

sqrt(x^2) = ±sqrt(4)

x = ±2
