Using (n-2)180 to find total number of degrees in a 5-sided shape
n= number of sides
(5-2)180=540degrees
So to find x, 100+160+80= 340
540-340=200
So 8x+8+5x+10=200 and solve for x
It has infinite lines of symmentry
80
80 is the answer.
P = 80
40 = 1/2 X p
40 X 2 = p
80 = p
I hope this helps!!!
Answer:
3.92$
Step-by-step explanation:
The first step is to deduct 20% of 4.50 from 4.50.
20% of 4.50 is 0.2 x 4.50 = .90
4.50 - 0.90 = 3.60
That's the new price without the sales tax.
Now we need to add 9% of 3.60 to 3.60 to get the final cost.
9% of 3.60 is .09 x 3.60 = 0.32
3.60 + .32 = $3.92
