Question

sin x=4/5 है तो tanx+cosx=?

Answer 1

$sinx = 4 \div 5 \: means \: it \: is \: a \: right \: angled \: \: trangl e \: whose \: perpencular \: is \: = 4 \: and \: hypatneous \: = 5 \\ by \: applying \: pythagore \: theorm \: \\ base \: = 3 \\ so \: tanx = 4 \div 3 \: an d \: cosx = 3 \div 5 \\ an d \: tanx + cosx = (4\div 3) +( 3 \div 5) = 29 \div 15$
