Question

In the given figure, find the value of 'x'.?



​

Answer 1

Step-by-step explanation:

let the 3rd angle of triangle be y.

then :

60+55+y =180 (angle sum property of trianlgle)

115+y=180

y = 180-150

y=65

then x =

y+x=180 (linear pair)

x=180-65

x=115

Answer 2

60 + 55 = 115. because sum of interior opposite angles of a triangle is equal to exterior angle so answer is 115
