Question

( tan left(100^{circ}+125^{circ}right)=tan 225^{circ} )
( begin{aligned} a operatorname{ls} 0, & tan 225^{circ} tan left(180^{circ}+45^{circ}right) &=tan 45^{circ} &=1 end{aligned} )
( cos frac{tan left(00^{circ}+tan 125^{circ}right)}{cos 100^{circ} tan 128^{circ}}=1 )
( tan 100^{circ}+tan 125^{circ}+tan 100^{circ} tan 125^{circ}=1 )

# 24. tani 100' + tan 125'+ tan 100', tan 125' is eapeal to
