a) SEN £ = 8/10 = 4/5 = 0,8
b) COS £ = 6/10 = 3/5 = 0,6
c) TG £ = 8/6 = 4/3 = 1,33
d)SEN £ = same with pts a
Cos £ = same with pts b
f)SEN B = 6/10 = 3/5 = 0,6
g)COS B = 8/10 = 4/5 = 0,8
H)TG B = 6/8 = 3/4 = 0,75
i)SEN B = same with pts f
COS B = same with pts g
b) COS £ = 6/10 = 3/5 = 0,6
c) TG £ = 8/6 = 4/3 = 1,33
d)SEN £ = same with pts a
Cos £ = same with pts b
f)SEN B = 6/10 = 3/5 = 0,6
g)COS B = 8/10 = 4/5 = 0,8
H)TG B = 6/8 = 3/4 = 0,75
i)SEN B = same with pts f
COS B = same with pts g
SEN² B +COS² B?
SEN² B +COS² B = 1
(3/5)²+(4/5)² =9/25 + 16/25 = 25/25 = 1
