Answer:
9 Sides
Step-by-step explanation:
According to the Question,
- Given That, The sum of the interior angles(s), in an n-sided polygon can be determined using the formula s=180(n−2), where n is the number of sides
Therefore, The sides do a polygon have if the sum of the interior angles is 1,260°.
Put The Values in Formula, we get
1260=180(n−2)
n-2 = 7
n=9 (9 Sides)
To reduce a fraction, divide the numerator and the denominator equally until they reach the simplest whole number possible.
In this case, the numerator (720) and the denominator (1080) can both be divided by 360 to get 2/3, our reduced fraction.
Andrew walked for 3/4 miles after his break
<h3>
How to calculate the number of miles Andrew walked after the break ? </h3>
Andrew went for a walk
The trail he took is 1 1/4 miles long
He walked for 1/2 miles before stopping for a water break
After the break, he continued the journey
He continued the journey without stopping
The distance Andrew walked after his break can be calculated as follows
5/4 - 1/2
= 5-2/4
= 3/4
Hence Andrew walked for 3/4 miles after taking the break

Answer:
Step-by-step explanation:
b.) cos((π/2)-Ф)=-3/5 is true because :
cos((π/2)-Ф)= sin(Ф)
False
(5,5)
y < x + 3
5 < 5 + 3
5 < 8 (correct)
(5,5)
y > -2x - 1
5 > -2(5) - 1
5 > -10 - 1
5 > -11 (correct)
so (5,5) is a solution..and there are many more
