<h3>Answer:  2300</h3>

Work Shown:

_{n} C _{r} = \frac{n!}{r!(n-r)!}\\\\_{25} C _{3}  = \frac{25!}{3!*(25-3)!}\\\\_{25} C _{3}  = \frac{25!}{3!*22!}\\\\_{25} C _{3}  = \frac{25*24*23*22!}{3!*22!}\\\\ _{25} C _{3}  = \frac{25*24*23}{3!}\\\\ _{25} C _{3}  = \frac{25*24*23}{3*2*1}\\\\ _{25} C _{3}  = \frac{13800}{6}\\\\ _{25} C _{3}  = 2300\\\\

Hello!

Since the shape has 6 points it is a hexagon

The sum of the angles in a hexagon add to 720

You add all the angles you know

102 + 133 + 117 + 170 + 90 = 612

Subtract this from 720 to find b

720 - 612 = 108

The answer is B) 108°

Hope this helps!

Find the parallel line to 5y-15x=-20 that goes through the point (3,-6).
Shtirlitz [24]
5y-15x=-20
5y=15x-20
y=3x-20/3
Slope = 3

Slope Intercept Form
y-y1=m(x-x1)
Therefore y-(-6)=3(x-3)
y+6=3x-9
y=3x-15

y=mx+b

m=slope or gradient (=-3)

y=-3x+b  

Add your points

(2, -1)

-1=(-3 x 2)+b

-1= -6+b

-1+6=b

b=5

y=-3x+5
