Question

In the quadrilateral ABCD , angle DAB= angle DCX=120°.If angle ABC=105°,what is angle ADC equal to?
A) 45°
B) 60°
C) 75°
D) 95°​

Answer 1

Answer:

75⁰

Step-by-step explanation:

120+BCD=180⁰ (LINEAR PAIR)

BCD=180-120

BCD=60⁰

sum of all angles of quadrilateral=360⁰

120+60+105+ADC=360

285+ADC=360

ADC=360-285

ADC=75⁰
