Answer:(1) The correct option is b. (2) The correct option is c.
Explanation:
(1)
It is given that the △ABD≅△FEC.
So by (CPCTC) corresponding parts of congruent triangles are congruent.
[tex]\angle CFE=\angle DAB[/tex]
It is given that the angle DAB is 63 degree.
[tex]\angle CFE=63^{\circ}[/tex]
Therefore, the correct option is b.
(2)
It is given that the △ABD≅△FEC.
So by (CPCTC) corresponding parts of congruent triangles are congruent.
[tex]BD=EC[/tex]
[tex]BD=CD+DE[/tex]
[tex]BD=8+10[/tex]
[tex]BD=18[/tex]
Therefore, the correct option is c.
