Answer:
1. 60 degrees
2. 30 degrees
3 .120 degrees
4. 135 degrees
Step-by-step explanation:
Supplementary angles add up to 180
No 1 .180÷3=60 degrees
Angle A=60degrees
No 3 .24+36=60
180-60=120
Angle A=120 degrees
No 2 . Compulsory angles add up to 90
90÷3=30 degrees
Angle A = 30 degrees
No 4 the angles on the diagram add up to 360 degrees
One is 90 degrees
The 2nd and 3rd are equal
360-90=270
270÷2=135 degrees
