Question

2) Find the value of x in the given figure​

Answer 1

Answer:

the value of the external angle is equal to the sum of the opposite interior angles

therefore , 80 + x = 120

or , x = 120 - 80

or, x = 40

Answer 2

Answer:

80 +120= 180(because sum of all interior angle of triangle is 180)

200= 180

=180-200 = 20

answer is 20 degree .
