Keegan needs to choose a code for her safe. She is allowed to pick a code between 3 and 8 digits long (a "digit" is any of the numbers 0 through 9). Keegan wants to keep the code as short as possible while maintaining good security. What is the least number of digits Keegan can pick for her code so that a potential thief has no more than a 0.0001% chance of breaking into her safe on the first attempt?

(-1,-0.5)

step-by-step explanation:

853.3

step-by-step explanation:

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

answer: -0.5 would be the most likley outcome
