How do i solve this problem? am i supposed to use tan, sin, or cos?

cos(45) * 28 = 14√2 or 19.8

Step-by-step explanation:

You have the hypotenuse and you want to find the adjacent side b. Out of Soh, CaH and ToA, you know it is CaH because you want the adjacent and have the Hypotenuse (a and H).

If you put CaH into a triangle and cover up the A, you will see that it would be C * H. If you put that into a calculator and substitute in the values you get cos(45) * 28 = 14√2

$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
