Find the cosine ratio of angle Θ. Clue: Use the slash symbol ( / ) to represent the fraction bar, and enter the fraction with no spaces.

The answer to your question is     cos Ф = 3 / 5

Step-by-step explanation:

Data

hypotenuse = 5

Adjacent side = 3

Opposite side = 4

Process

1.- Remember the trigonometric function cosine

           cosine Ф = Adjacent side / hypotenuse

2.- Substitution

            cos Ф = 3 / 5

3.- Conclusion

    The cosine of Ф is 3/5

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
