In a given figure *ST || QR*, *PS *=* *2 cm
and *SQ* = 3 cm.
Then the ratio of the area of Δ*PQR* to the area
of Δ*PST* is

In the adjacent figure ∠*BAC* = 90° and *AD* ┴ *BC*
then

In the given figure, *PR
*=* *26 cm, *QR *=* *24* * cm. ∠*PAQ *=* *90°* *,*
PA*=6* *cm and* QA *=* *8* *cm. Find* *∠*PQR*
