Let Angle ABC be 2x, Angle EBC be 5x

$angle \: dbc = 90 - 2x \\ angle \: dbc \: + angle \: ebc = 180 \\ 90 - 2x + 5x = 180 \\ 3x = 90 \\ x = 30 \\ \\ angle \: dbc = 90 - 60 \\ = 30$

Answer:

$x = \frac{6 \pm \sqrt{(-6)^2 - 4(3)(8)}}{2(3)}$

Step-by-step explanation:

Given the equation, $3x^2 - 6x + 8 = 0$ , the quadratic formula for solving this equation is given as:

$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

Where,

a = 3

b = -6

c = 8

Plug in the above values into the quadratic formula.

$x = \frac{-(-6) \pm \sqrt{(-6)^2 - 4(3)(8)}}{2(3)}$

$x = \frac{6 \pm \sqrt{(-6)^2 - 4(3)(8)}}{2(3)}$
