Question

In the given figure ,PQRS is a rhombus with AngleSRQ=72 and SQ extend till such that angleQPT=20.find y​

Answer 1

Step-by-step explanation:

In △TPS and △TRQ

∠PST=∠RQT

∠SPQ=∠QRT

[∵ exterior angle of cyclic quadrilateral is equal to the interior opposite angle]

∠T=∠T (common)

∴△TPS−△TRQ (By AA)
