So first six sided polygon is called hexagon.
and the sum of all interior angles in a hexagon is 720°
so if you divide that by six. since it has six interior angles,
the angle of each interior angle will be 120°
as of exterior angle.
*note: the sum of the interior angle and its corresponding angle is always 180°
so if you subtract 120° from 180°
you have 60°
so all exterior angles are 60°

Two trains 500 miles apart accidentally are on the same track heading toward each other. The passenger train is traveling 80 mph
Natalka [10]

Answer:

2 miles

Step-by-step explanation:

Their combined speed (speed of closure) is 80 mph + 40 mph = 120 mph.

120 mi/h = 120 mi/(60 min) = 2 mi/min

The distance between the trains at the 1-minute mark is ...

(1 min) · (2 mi/min) = 2 mi

They were warned when two miles apart.

If 2k, 5k-1 and 6k+2 are the first 3 terms of an arithmetic sequence, find k and the 8th term.
Simora [160]
Consecutive terms in an arithmetic sequence differ by a constant d. So

5k-1=2k+d
6k+2=5k-1+d
\implies\begin{cases}3k-d=1\\k-d=-3\end{cases}\implies k=2,d=5

Denote the n-th term in the sequence by a_n. Now that a_1=2, we have

a_n=a_{n-1}+5=a_{n-2}+2\cdot5=\cdots=a_1+(n-1)\cdot5

which means

a_8=2+(8-1)\cdot5=37

A point G on a segment on a segment with endpoints F(4, 8) and H(10, 12) partitions the segment in a 3:4 ratio. Find G. You must
Andru [333]

Suppose, we are given

two points as

F as (x1, y1)

H as (x2, y2)

assume  it divides  in m/n

we can use formula

G=(x,y)=(\frac{mx_2+nx_1}{m+n}, \frac{my_2+ny_1}{m+n})

now, we are given points as

F=(x1, y1)=(4,8)

x_1=4,y_1=8

H=(x2, y2)=(10,12)

x_2=10, y_2=12

\frac{m}{n} =\frac{3}{4}

so,

m=3,n=4

now, we can find  

x=(\frac{3*10+4*4}{3+4}, y=\frac{3*12+4*8}{3+4})

x=\frac{46}{7} , y=\frac{68}{7}

so, point is

G=(\frac{46}{7} , \frac{68}{7}).................Answer
