In ΔEFG, \overline{EG} EG
is extended through point G to point H, \text{m}\angle EFG = (2x+1)^{\circ}m∠EFG=(2x+1)
∘
, \text{m}\angle FGH = (6x+2)^{\circ}m∠FGH=(6x+2)
∘
, and \text{m}\angle GEF = (x+19)^{\circ}m∠GEF=(x+19)
∘
. Find \text{m}\angle GEF. m∠GEF.

25

Step-by-step explanation:

(6x+2)=(x+19)+(2x+1)

6x+2)=(x+2x)+(19+1)

6x+2=  3x+20

−3x+2= −3x

3x+2= 20

3x=  18

x=  6

m∠GEF = x+19 = (6)+19 = 25  

X+19=(6)+19=25

b

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
