Answer:
0.2y+10
Step-by-step explanation:
D. 54° as you know an external angle has to equal up to 360
when you start plugging in 360 by 36 gives you 10
360 by 40 gives you 9
360 by 45 gives you 8
360 by 54 gives you 6.666 repeating you know that it isn't possible
you cannot have a repeating number of sides as an angle measure
that's how you get that answer
First: do .25 (1/4) times 36
Second: subtract 36 from that #
Third: Check ur work
That is ur answer
