Answer:
66
Step-by-step explanation:
Find the last side of the triangle using the Pythagorean theorem.

B=
This makes b = 18.3
Now you can find the angle B = arcsin (opp/hyp)
B=arcsin 
B= 66.42

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: <em>180° - 156° </em>
This will equal 24°
Now you have 2 angles inside the triangle, 108° and 24°
Add those 2 numbers: <em>108° + 24°</em>
This will equal 132°
All triangles must equal to 180°
So you subtract: <em>180° - 132°</em>
Which will equal 48°.
