Answer 1

Answer:

First Name the points of the triangle as ∆ ABC

Step-by-step explanation:

120 + <A = 180°. { linear pair}

<A = 180°-120°

<A = 60°

120°+ <B = 180° { linear pair}

<B = 180°-120°

<B = 60°

Now in ∆ABC,

<A+<B+<C = 180° { angles sum property}

60°+60°+<C = 180°

<C = 180°-120°

<C = 60°

Now by linear pair,

x + <C = 180°

x + 60° = 180°

x = 180°-60°

x = 60°

hope it helps...........:)

Answer 2

Answer:

120º

Step-by-step explanation:

Sum of exterior angles of a triangle is 360.

120+120+x=360

240+x=360

x=360-240

x=120º
