The campbell family has a disposable income of $60,000 annually. assume that their marginal propensity to consume is 0.8 (the campbell family spends 80% of new disposable income on consumption) and that their autonomous consumption spending is equal to $10,000. what is the amount of the campbell family\'s annual consumer spending? ,

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
