Answer:

Q1

Angles forming a linear pair are supplementary and sum to 180°

  • x + 8x = 180°
  • 9x = 180°
  • x = 20°

The smaller angle is 20°

Q2

A(-2, 10) reflected over x-axis

Rule for such a reflection is:

  • (x, y) → (x, -y)

Point A will map to:

  • (-2, 10) → (-2, -10)

Correct option is D

Q3

One point is at the origin and two other points are at the distance m horizontally and vertically from the origin

The last point will have same distance m from the point (m, 0) and (0, m) and this will be point:

  • (m, 0 + m) = (m, m)
