Answer:
26°
Explanation:
The angle 123° is on a straight line. All angles on a straight line add up to 180°, so the first thing you should do is subtract 123 from 180.
(180-123)
Now, your answer should be 57°, and that is equal to angle W.
You now know two angles. Angles in a triangle add up to 180°, too, so all you do now is the following:
97 + 57 = 154
180- 154 + 26
And there's your answer!
