What is an equation i can use the find the rate of interest? "A = P(1 + rt)" is what i see when i look it up but how to i find "r" if that is what i am solving for to begin with?

where did you get them? if you picked from the grass, is is probably poisonous.

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

might be the correct answer will be question number 2
