Step-by-step explanation: 10sin(25-x) = 6sin (18+x) sin(25-x) /10 = sin (18+x)/6 by cross multiplication 6(25-x) = 10(18+x) 150 -6x = 180+ 10x 150-180 = 10x +6x -30 = 16x x = -30/16 Reply

Step-by-step explanation:10sin(25-x) = 6sin (18+x)

sin(25-x) /10 = sin (18+x)/6

by cross multiplication

6(25-x) = 10(18+x)

150 -6x = 180+ 10x

150-180 = 10x +6x

-30 = 16x

x = -30/16
