(9).. tan theta=p/b=2/1
sec theta=h/b=√5/1=√5
[10] sin60=√3/2
(12).. Sec theta=h/p=13/12 :
p=√13^2-12^2=√25=5
tan theta=p/b=5/12
is your answer
13...sin90=1
14..tan<6cos^2theta
sec theta=h/b=√5/1=√5
[10] sin60=√3/2
(12).. Sec theta=h/p=13/12 :
p=√13^2-12^2=√25=5
tan theta=p/b=5/12
is your answer
13...sin90=1
14..tan<6cos^2theta
