Answer:
1=60 degrees, 2=60 degrees, 3=120 degrees 4=67 degrees, 5=23 degrees 6=37 degrees
Step-by-step explanation:
180 degrees in any triangle
1: 180-(49+71)
2: 1 and 2 are opposite and opposite angles are equal
3: 360 -(angle 1+angle 2) then divide by 2
4: 180-(53 + angle 2)
5: 180-(angle 3+angle 6)
6: 90 degrees in a right angle so 90 degrees - 53 degrees
