what is the sum of the exterior angles of a 25-gon?

a. 180

b. 360

c. 4,140

d. 165

C

Step-by-step explanation: Subtract 2 from 25 to get 23. Then, multiply by 180. This equals 414p

As for the 19-gon, the sum is 360

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

$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
