Question

Two adjacentangles on a straight line are in the ratio 11:7 Find the
measure of each of these angles​

Answer 1

Answer:

110* and 70*

Step-by-step explanation:

On any line, sum of angles is 180*.

  Let the angles are 11a and 7a.

Their sum = 180*

 ⇒ 11a + 7a = 180*

 ⇒ 18a = 180*

 ⇒ a = 180/18 = 10*

Hence angles are:

    11a = 11(10*) = 110*

     7a = 7(10*) = 70*
