Write down all the subsets of {q, r,s}.

{q, r, s} consists of 3 elements, so there are 2³ = 8 possible subsets.

• empty set: { }

• every possible singleton set: {q}, {r}, {s}

• every possible pair: {q, r}, {q, s}, {r, s}

• the set itself: {q, r, s}

0.32

step-by-step explanation:

2.24/7

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
