Answer:

a = 26°

Explanation:

a and 154° are adjacent angles on a straight line and sum to 180°, so

a + 154° = 180° ( subtract 154° from both sides )

a = 26°

Answer:

26

Explanation:

angle a and 154° both are supplementary. You see the straight line? Yes, once you combine 154° and a, you will get the straight line or straight angle which is 180°.

Therefore:-

154+a=180

a=180-154

a=26
