Answer:
43°
Explanation:
-the interior angle of a triangle always adds up to 180°
- angles that form a straight line always adds up to 180°
- the angle at 75° has the angle of 105° to add up to 180°
- the triangle needs a full degree of 180, but only affs up to 137° (105° + 32°) so you have to subtract the 137° from the total amount you need(180°) which gives you the answer of 43°
