Answer:
88°
Step-by-step explanation:
RULES:
- angles on a straight line add up to 180 degrees
- angles in a triangle add up to 180 degrees
so.
because of rule 1, we do 180-120 to get 60, to get that right corner angle. Now, we know 2 angles. So, (because of rule 2), we can do 60+32 = 92, and 180-92 = 88
So, 1 = 88
Hope this helps! If it doesn't make sense, feel free to ask me to explain it further.
