Answer:

x = 110°

Step-by-step explanation:

Adjacent angles sum to 180°

Thus 3 of the interior angles are

180° - 50° = 130°

180° - 110° = 70°

180° - 90° = 90°

The sum of these interior angles is

130° + 70 ° + 90° = 290°

The sum of the interior angles of a quadrilateral = 360° , then

fourth interior angle = 360° - 290° = 70°

Thus x = 180° - 70° = 110°

Answer:

${2x}^{3} - {12x}^{2} - 18x + 28$

Step-by-step explanation:

$(2x + 4)( {x}^{2} - 8x + 7) \\ = {2x}^{3} - {16x}^{2} + 14x + {4x}^{2} - 32x + 28 \\ = {2x}^{3} - {12x}^{2} - 18x + 28$

What is the slope of the line that is perpendicular to the line whose equation is 3x + y = 4?

Luba_88 [7]

Answer:

1/3

Step-by-step explanation:

3x + y = 4

y = -3x + 4

the perpendicular slope is the reciprocal of the original slope.

so the slope would be 1/3
