Question

( cos P=frac{1}{7}, cos Q=frac{13}{14} mid sin ^{2} alpha alpha )
( cos (P-Q)=cos P cos theta+sin P sin theta )
( rightarrow frac{1}{7} times frac{13}{14}+frac{sqrt{48} times 27}{7 times 14} )
( cos (p-a) frac{36+13}{98}=frac{49}{982} )
( P-Q=60 )

# 035) COSP= P&o are achte angle P-Q=? 675 30 BX 60 10 47 i sinpa JY 8 eu
