3 sides

Step-by-step explanation:

The sum of the exterior angles add up to 360°:

The exterior angles of this shape would be 180 - 60 = 120:

So the number of sides is 360 ÷ 120 = 3 sides

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
