Answer 2

Answer:

x = 135° & Y = 80°

Step-by-step explanation:

sum of interior angles of triangle = 180°

A/Q :-

=> <BAC + <ABC + <ACB = 180°

=> 50°+ 30° + <ACB = 180°

=> <ACB = 180° - 80°

=> <ACB = 100°

Value of Y = 180 - 100 as in linear pair .

Value of Y = 80°

Sum of Y and <55° = x because the sum of two interior angles of a triangle is equal to the opposite exterior angle

=> x = 80°+55°

=> x = 135°
