A linear pair of angles is in the ratio 9 :11. The measure of the smaller angle in degrees is?


BTW there is a Hint
Assume the angles to be 9x° and 11x°.
Can you help me ASAP

Answer:

  81°

Step-by-step explanation:

Angles in a linear pair are supplementary. That means their total is 180°.

  9x° +11x° = 180°

  x = 180/20 = 9

Then the smaller angle is ...

  9x° = 9·9° = 81° . . . . measure of the smaller angle

Additional comment

The larger angle will be 11·9° = 99°.
