This time i inserted the picture.

can someone me! it's law of cosines, and i'm having to use the formula but i do not know which side length is a, b and c. in the last question, i was given the angles and that's how i figured out which side length is which. all i'm given is two side lengths and an unlabeled angle. so me someone!

You use the law of cosines whenever you're given a SAS triangle. The formula is

C is the given angle, c is the side opposite this angle, and a/b are the given sides adjacent to angle C.

In this case, if is the length of the missing side, then

36 is the final answer! : )

$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
