Aladder leans against a brick wall. the foot of the ladder is 7 feet from the wall. the ladder reaches a height of 22 feet on the wall. what is the angle the ladder makes with the wall? (to the nearest tenth) a) 15.4° b) 17.7° eliminate c) 18.6° d) 21.5°

the answer is 17.7

Step-by-step explanation:

Apply tanθ =  

opposite

adjacent

tanθ =  

7

22

θ = tan−1(

7

22

)

θ = 17.7°

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
