Question

if theta is an acute angle such that cos theta =3/5 then find sin theta tan theta -1 whole divided by 2tan square theta

Answer 1

4/4×4/3-1/2(4/3)sq.
4/3-1/32/9
4-3/3=1/3
/32/9=3/32
Nd second answer
4/4×4/3-1/2×16/9
16/12-1/32/9
4/12/32/9
3/2 ya fir 2/3

Answer 2

given cos Q= 3/5=b/h
here b =3,h=5
now using Pythagoras gorgeous theorem
we get p =4
now sin Q =p/h
= 4/5

now putting it u can solve it

hope it will help u
