Solve for x in the diagram below.
3x
80°
2x
x =

160/3 degrees

Step-by-step explanation:

(80/3) ×2 =160/3 degrees

80 divided by 3 which mean 80 divides into 3 parts.

We get 2 parts of the 80, so that we times 2.

idk

step-by-step explanation:

do it yourself, cause that made me do it myself today, in english!

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
