Question

pls seng it asap. it is very urgent

Answer 1

Answer:

c) 105

Step-by-step explanation:

take the ∆ABD and ∆BCD

angle B=108=54 x2

angel D=42=21x2

so triangle ABD=54+21+x=180

x=105

If AB=BC

so Angel A=angel C

then it 105

Answer 2

Answer:

The figure is a kite and in a kite 1 pair of angles are equal

angle A & angle C are equal.

So, 108+42=150°

Quadrilateral has 360° of interior angle

So, angle BCD is

2x + 150 = 360

2x = 360 - 150

x = 210/2

x = 105°

Angle BCD = 105°

Or in your case option C
