Answer 2

Hello,

The answer starts here.......

A + B = 108
B + C = 130

SO,

Adding the above two we get:


A + B + B + C = 108 + 130
A + B + C + B = 238

180 + B = 238
(since we know that angle sum property of triangle is 180.
Hence, angle a + b + c is equal to 180 degree)

B = 238 - 180 = 58


Now,
From first given condition

A + B = 108
A = 108 - B
A = 108- 58 = 50

Again we have,
C = 130 - B
C = 130 - 58 = 72

SO,
A = 50
B=58
C= 72

Hope this will be helping you ✌️
