1. 50°

2. 120°

I think it is right answer.

Answer 2

Answer:

16 .A

clearly angle BAC= 180-110

== 70°

Know external angle of a triangle is equal to sum of remaining internal angles

so

angleACD= angleBAC+ angleABC

120= 70+X

X = 120-70= 50

50° Ans

B.

angle ACD is external angle of triangle ABC

so angle ACD= 30+ 40= 70°

now in triangle ECD

angle

CED= 180-(70+50)

= 180- 120

= 60°

and X= 180-60= 120

thus 120° Ans
