Arnold recieved a bonus at work. He decided to put 12% of his bonus into a savings account. If Arnold put $180 into his savings account, how much was his whole bonus?

180 = 12%

divide both sides by 12

15 = 1%

1500=100%

$1500 is the whole bonus

3x + 4y -25 =0 represents the amount of change sianna should recieve

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
