Always draw a diagram first to help with clarity.Correct use of Sine Rule:sin(A)/BC = sin(C)/ABTherefore sin(C) = ABsin(A)/BC sin(C) = 20sin(70)/100 sin(C) = 0.188 (rounded to 3 Significant Figures) C = a...

5/6 + 3/7= ((5 x 7) + (3 x 6))/(6 x 7)= (35 + 18)/42= 53/42= 1 11/42

7x + 6 = 1 + 2x7x + 6 -2x = 15x + 6 = 15x = 1-65x = -5x = -1
