Answer:

It would be D. 110 degrees

Step-by-step explanation:

A triangle is always equal to 180 degrees. So, if you add b + c, you get 70 degrees. Subtract that from 180, and you get 110. Hope this helped!

Answer:

a = 110 degree

d= 70 degree

Step-by-step explanation:

a+b+c = 180. (being sum of all interior angle of a triangle is 180 degree)

a+40+30 = 180

a=180-70

a = 110

Similarly,

a+d=180. (being supplementary angle)

110+d=180

d= 70
