**#1.) Directions: Determine the following trig functior using the Unit Circle:
Draw the initial and terminal side
Label the reference angle in degrees
Draw the reference triangle
Annotate all sides of the triangle
Identify and simplify the trig ratio
sin 135 =

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
