Answer:
108°
Step-by-step explanation:
1) Find a
180 - 44 = 136 (angles in a triangle add to 180° - the sum of the other 2 angles must be 136°)
Angles on a straight line add up to 180° so 2a + x = 180° → x = 180 - 2a
(a + 10) + (180 - 2a) = 136
-a + 190 = 136
-a = 136 - 190
-a = -54
a = 54°
If a = 54°, then 2a = 54 × 2 = 108°
