Answer:

122.5 degrees

Step-by-step explanation:

A six sided polygon's interior angles sum to

  (n-2)(180) =  (6-2) (180) = 720 degrees

then   x + x + x +     x+10    + 130   + 90 = 720

                          4x = 490        so x = 122.5 degrees

1) John is going golfing and needs to rent equipment. It costs him $75 to rent the clubs and he needs to purchase golf balls for
daser333 [38]

Answer:

Step-by-step explanation:

So he has $100 and you want to see how many golf balls he can purchase well we know he spends $75 on the clubs so

 75

-100

--------

  25

John now has 25 dollars left. One ball is $1.50 so we keep adding or multiplying till we finish 25 dollars

1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 = 24

or

  1.50

x    16

----------

    24

he can purchase 16 golf balls

and the reason why it's 16 is that 16 golf balls are equal to 24 dollars and he can't purchase 17 golf balls or else that would be $25.50 which is more money than he has.

Hope that helped!
