its c because i already did that and got it right
sorry ya please forgive me
78
∠A + ∠B + ∠C = 180 { Angle sum property of triangle}
42 + ∠B + 60 = 180
∠B + 102 = 180
∠B = 180 - 102 = 78
In similar triangles, corresponding angles are congruent.
∠S ≅ ∠B
∠S = 78°
No coz 2:3 is 2+3=5
1:2 is 1+2=3 so they are not equivalent.
