Reference angle

Find the reference angle of each angle:

Correct answer:

436°ref =  76 °
862°ref =  38 °
402°ref =  42 °
1200°ref =  60 °
736°ref =  16 °
980°ref =  80 °
182°ref =  2 °

Step-by-step explanation:

436°ref = 76°ref = 76° (Q1)
862°ref = 142°ref = 180° - 142° = 38° (Q2)
402°ref = 42°ref = 42° (Q1)
1200°ref = 120°ref = 180° - 120° = 60° (Q2)
736°ref = 16°ref = 16° (Q1)
980°ref = 260°ref = 260° - 180° = 80° (Q3)
182°ref = 182° - 180° = 2° (Q3)
