Question

3. In Fig. 10.16, if LABD = 70°, ZADB = 30°, then ZBCD is equal to
(a) 80°
(b) 110
(c) 120°
(d) 100​

Answer 1

Answer:

i think 80° is the correct answer

mark it's brainliest please

Answer 2

Answer:

option a will be the answer answer is 80 .

Step-by-step explanation:

Here angle B is 70

and angle c is 30

therefor, ABC is a triangle

since. ABC is a triangle therefor, all angle a triangle is 180 degree

here. two angle is given the sum of the two angle is 100 degree.

therefor, 180 minus 100 equal to 80 degree.

angle a equal to angle (alternative angle)

there for, angle c is 80
