In triangle ABC, points D,E,F are on sides BC,CA,AB respectively such that AD,BE,CF are angle bisectors of triangle ABC. The linesAD,BE,CF are concurrent at I,the incenter of triangle ABC. If Angle BAC=90, what is the measure (in degrees) of Angle EIF?

IN ABC, m<BAC =3x+9, m<ABC =8x+11, and m<BCA= 5x8. Find the measures of <1,<2,<3. SHow your woek for solving x and finding each angle measure clearly.
