Answer:
48
Step-by-step explanation:
The 156° angle will help you in this problem.
On the opposite side, you have to find the number that equals to 180°
So that'll be: 180° - 156°
This will equal 24°
Now you have 2 angles inside the triangle, 108° and 24°
Add those 2 numbers: 108° + 24°
This will equal 132°
All triangles must equal to 180°
So you subtract: 180° - 132°
Which will equal 48°.
