Step-by-step explanation:
36A) AB = 4/ sin 30° = 4/ 0.5 = 8 cm
36B) AC = 4/ tan 30° = 4/ 0.577 = 6.9 cm
36C) BD = 4/sin 45° = 4/ 0.707 = 5.7 cm
36D) area of ∆ABC = ½×6.9×4= 13.8 cm²
36E) sin A = sin 30° = 0.5

Answer:
c
Step-by-step explanation:
160 = 16 * 10 = 4 * 4 * 2 * 5 = 2 * 2 * 2 * 2 * 2 *5

Set the two values equal to each other with 18x-2=12x+2 and then plug it in to the equation and solve
