Answer 2

Answer:

B= 50 degrees and c = 70 degrees

Step-by-step explanation:

First find b, To find b:

b + d= 180 degrees (linear pair)

b + 130 = 180,

b = 180-130 ;   b = 50 degrees

Thus , we got b = 50 degrees.

To find c:

a+b+c = 180 degrees ( sum of all the angles in a triangle are always 180 degrees)

a = 60 degrees, b = 50 degrees, so..

a+b+c =180 degrees.

60+50+c = 180

110+ = 180

c = 180-110

c = 70 degrees.

Hence, proved.
