tan theta =12/5
= p/b
so
p= 12
b= 5
now
h square = p square+ q square
h square = 144+25
h square = 169
h. = 13
then we have to find the value of
5 sin theta -12 cos theta. (1)
sin theta= p/h
= 12/13
cos theta = b/h
= 5/13
now
putting in eq (1)
=5*12/13- 12*5/13
=60/13-60/13
= 0 is the ans
= p/b
so
p= 12
b= 5
now
h square = p square+ q square
h square = 144+25
h square = 169
h. = 13
then we have to find the value of
5 sin theta -12 cos theta. (1)
sin theta= p/h
= 12/13
cos theta = b/h
= 5/13
now
putting in eq (1)
=5*12/13- 12*5/13
=60/13-60/13
= 0 is the ans
