In a`triangleDEF`, if `angleE=105^(@)` and `angleF=40^(@)`,find `angleD`

In the following, CDEF is a cyclic quadrilateral. bar(CG) and bar(DH) are the angle bisectors of angleC and angleD respectively. If angleE=100^(@) and angleF=110^(@) , then find angleCPD .

In the following figure, if PQ || RS, angle MXQ=135^(@) and angle MYR=40^(@) . Find angle XMY .

If triangleABC and triangleDEF are similar triangles such that angleA =45^@ and angleF =56^@, then find angle C

In figure, if QT bot PR, angle TQR =40^(@) and angle SPR =30^(@) , find value of y-x
