Answer 2

Answer:

x=100°

Step-by-step explanation:

1) there is direct formula,

exterior angle = sum of two internal angle

here, x= (55+45) = 100

2) alternativemethid

sum of angle of triangle = 180°

=> 45+55+A= 180

=> A= 180-100 = 80°....{ A is third angle of triangle}

now , A+x = 180° .

=> x = 180-A

=> x=100°
