# Reference angle

Find the reference angle of each angle:

Result

1175°ref =  85 °
101°ref =  79 °
1171°ref =  89 °
463°ref =  77 °
730°ref =  10 °
1496°ref =  56 °
761°ref =  41 °

#### Solution:

1175°ref = 95°ref = 180° - 95° = 85° (Q2)
101°ref = 180° - 101° = 79° (Q2)
1171°ref = 91°ref = 180° - 91° = 89° (Q2)
463°ref = 103°ref = 180° - 103° = 77° (Q2)
730°ref = 10°ref = 10° (Q1)
1496°ref = 56°ref = 56° (Q1)
761°ref = 41°ref = 41° (Q1)
