<h3>
Answer: 130</h3>
===========================================================
Explanation:
There are two approaches here.
Method 1
Focus on the numbers along the top only.
The left arrow points at 50 while the arrow on the right points at 180. Subtract these numbers to get 180 - 50 = 130
------------------------------
Method 2
Focus on the numbers along the bottom row this time.
The left arrow points at 130 and the right arrow points at 0
The difference of which is 130 - 0 = 130
Because we're subtracting off 0, it means we can simply look at only one number without having to do any math. This only works if the other portion of the angle is pointing at 0 or 180.
------------------------------
Notice that 130 degrees is larger than 90, so this angle is obtuse. This means that if you aren't sure whether to go with 50 or 130, it will depend on if it's acute or obtuse.
