    i dont know how to use the symbols they give lol but ill type properly angle a is 70 degrees angle c is 60 degrees sine rule = A/sin(a) = B/sin(b) = C/sin(c) the side opposite angle a = side A same for B and C we have x=B and 15=A so the rule is 15/sin(70) = x/sin(60) multiply by sin(60) this gives 15sin(60)/sin(70) = x x=13.8
