Answer:

x=11

Step-by-step explanation:

  • The angles directly opposite 80 and 60 are also 80 and 60 respectively, because they are vertical angles
  • Now the triangle we see there, on the bottom left corner the angle is 80 degrees and the bottom right the angle is 60 degrees
  • Theorem states that the sum of angles in a triangle is 180 degrees
  • So 80 degrees plus 60 degrees plus the angle (x+51) is equal to 180
  • 80+60+(x+51)=180\\x+80+60+51=180\\x+191=180\\x+191-(191)=180-(191)\\x=11

Which of the following systems of inequalities would produce the region
Debora [2.8K]

Answer:

Step-by-step explanation:

Neither blue plot line is dashed, so we eliminate any equation that contains the symbols "<" or ">". Remove A and C

B and D (actually all options) have y ≤ -x + 4 which is a line with slope -1 any y intercept 4. This represents the area below the line running from (0, 4) to (4, 0)

Which leaves us to select from y ≥ x + 2 for option B or y ≤ x + 2 for option D

As the shaded area is <em>below</em> the line we choose <u>option D</u>
