Name and expression that is equivalent to sin < r explain! answer asap

Sin R  = Cos S

Step-by-step explanation:

Sin R = opposite side/ hypotenuse

          = ST/SR

Cos R = adjacent / hypotenuse

        = TR / SR

Tan R = opposite / adjacent

         ST/TR

Sin S = opposite side/ hypotenuse

          = TR/SR

Cos S = adjacent / hypotenuse

        = ST / SR

Tan R = opposite / adjacent

         TR/ST

Sin S = Cos R

Sin R  = Cos S

Tan S = 1/ Tan R

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

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
