List the reference angles for each of the following angles: For 15 degree, the reference angle is____For -55 degree, the reference angle is____For 202 degree, the reference angle is____For 415 degree, the reference angle is____For 160 degree, the reference angle is____

Solution

a)reference angle =15^o

b)reference angle =55^o

c)reference angle =202-180=22^o

d)reference angle =415-360 =55^o

e)reference angle =180-160=20^o
