Answer 1

The answer of the question is 60° which is option(A).

here,

let one be suppose angle a°

a°+ 120° = 180° {being straight angle}or, a° = 180° - 120°

or, a° = 60°

a° = 60°

Now,

Let angle S be s°

s°+60°+60° = 180°{ the sum of angle of triangle is 180°}

or, s° = 180° - 120°

or, s° = 60°

therefore, angle S is 60°

Answer 2

I believe it would be A: 60°.

Explanation:

I suck at explaining stuff but since R is 60°, and theres 120° outside of the triangle, that implies T = 60°. Triangles equal 180° so

60° + 60° + S = 180°

S = 60°

Hope this helps
