∠a and \angle b∠b are vertical angles. if m\angle a=(2x+1)^{\circ}∠a=(2x+1)
∘
and m\angle b=(8x-17)^{\circ}∠b=(8x−17)
∘
, then find the value of x.

Vertical angles are the same.

Set the two equations to equal each other ans solve for x:

2x + 1 = 8x -17

Add 17 to both sides:

2x + 18 = 8x

Subtract 2x from both sides:

18 = 6x

Divide both sides by 6:

x = 18/6

x = 3

the answer is 4.8 units on e2020.

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
