Question

Find the value of x.

  1. 9°
  2. 10°
  3. 11°
  4. 12°

hintHint:

In this question we have to find x. The two angles given are alternate exterior angles which are equal, using this we can equate the two equations and find x.

The correct answer is: 11°



    APQ,
    the two angles are alternate exterior angle.
    So they are equal.
    rightwards double arrow 3 x plus 28 equals 7 x minus 16
rightwards double arrow 28 plus 16 equals 7 x minus 3 x
rightwards double arrow space space space space space space space space 44 equals 4 x
rightwards double arrow space 44 divided by 4 equals x
rightwards double arrow space space space space space space space space space x equals 11
