Answer:
Step-by-step explanation:
5) x = 6sin45 = 6(√2)/2 = 3√2
y = 6cos45 = 6(√2)/2 = 3√2
6) x = 2√6sin45 = 2√6(√2)/2 = 2√3
y = 2√6cos45 = 2√6(√2)/2 = 2√3
7) x = 16sin60 = 16(√3)/2 = 8√
y = 16cos60 = 16(½) = 8
8) u = 2/sin30 = 2 / ½ = 4
v = 2/tan30 = 2/(1 /√3) = 2√3

Whole numbers greater than zero are called positive integers. Whole numbers less than zero are called negative integers. The integer zero is neither positive nor negative, and has no sign. Two integers are opposites if they are each the same distance away from zero, but on opposite sides of the number line.
