Justin is married with one child. he works 40 hours each week at a rate of $16 per hour. his wife began working part time after their daughter was born, but still contributes about $350 to the cash inflow each month. their monthly cash outflow is generally about $3,000. they have a balance of $2,000 in their savings account. justin has retirement contributions taken out of his paycheck at work. they have renter’s, car and life insurance coverage. based on this information, what part of their financial plan should justin and his wife work on? a. managing income b. managing liquidity c. protecting assets d. retirement.

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).
