Find the value of x .

​

9514 1404 393

  x = (23 1/3)°

Step-by-step explanation:

The sum of angles in a triangle is 180°.

  40° +2x +4x = 180°

  6x = 140° . . . . . . . . . . . subtract 40°

  x = 140°/6 = (23 1/3)° . . . . divide by the coefficient of x

This makes the angles be 40°, 46.67°, and 93.33° (rounded to hundredths).

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
