Maths Puzzle
If (sin theta + cos theta)/(sin theta - cos theta)=7, then the value of tan theta is equal to :
(A) 4/3
(B) 5/3
Read Solution (Total 2)
-
- (sin theta + cos theta)/(sin theta - cos theta)=7
or, 6 sin theta = 8 cos theta
or, sin theta/cos theta = 8/6
or tan theta = 8/6 = 4/3 - 12 years agoHelpfull: Yes(1) No(1)
- by componendo and devidendo
a/b=c/d====(a+b)/(a-b)=(c+d)/(c-d)
so by above expressiion tan(theta)=4/3 - 12 years agoHelpfull: Yes(0) No(1)
