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.

$\angle CFE=\angle DAB$

It is given that the angle DAB is 63 degree.

$\angle CFE=63^{\circ}$

Therefore, the correct option is b.

(2)

It is given that the △ABD≅△FEC.

So by (CPCTC) corresponding parts of congruent triangles are congruent.

$BD=EC$

$BD=CD+DE$

$BD=8+10$

$BD=18$

Therefore, the correct option is c.

kramer

Answer:

D. 10.91 square centimeters

Step-by-step explanation:

Area of a sector of a circle = $\frac{\theta}{360}\\$ $\pi$ $r^{2}$

where $\theta = 50^{o} C$

radius (r) = half of diameter = 10/2 = 5 cm

Area = $\frac{50}{360} * \frac{22}{7} * 5^{2}$

= 10.91 $cm^{2}$
