Ithink it's a, but i'm not 100% sure

➷ As it is six sided, we can use this equation to calculate the sum of interior angles:

(n - 2) x 180

n is the number of sides

(6 - 2) x 180 = 720

Add together all the given angles:

100 + 115 + 130 + 105 + 95 = 545

720 - 545 = 175

The correct option should be D. 175

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
