Question

Solve for x.

  1. 49
  2. 41
  3. 44.5
  4. 48

hintHint:

Linear pair of angles are formed when two lines intersect each other at a single point.

The correct answer is: 48


    They are a linear pair, so they are supplementary angles.
    2x + 1 + 83 = 180
    2x + 84 = 180
    2x = 180 – 84 = 96
    x = 48
    Hence, the correct option is (d).

    In math, a linear pair of angles are those two adjacent angles whose sum is 180°.

    Name a pair of angles that are vertical.

    They are always equal to each other. In other words, whenever two lines cross or intersect each other, 4 angles are formed. We can observe that two angles that are opposite to each other are equal and they are called vertical angles.
