Answer:

<CBD =75 degrees.

Step-by-step explanation:

I'm assuming that you want to know the value of <DBC

When a ray has the fixed end on a line, that ray will cut the line into 2 angles that total 180o.

In simpler language <ABD + <CBD = 180

<ABD = 105 degrees which is a given,
105 + <CBD = 180 Subtract 105 from both sides.
105-105 + <CBD = 180 - 105
<CBD = 75 Degrees Answer

Answer:

DBC = 75

Step-by-step explanation:

ABD and DBC are supplementary angles. They add to 180 degrees.

ABD + DBC = 180

105 + DBC = 180

Subtract 105 from each side

105-105 + DBC = 180-105

DBC = 75

The general solution of 2 y ln(x)y' = (y^2 + 4)/x is

Sav [38]

Replace $y'$ with $\dfrac{\mathrm dy}{\mathrm dx}$ to see that this ODE is separable:

$2y\ln x\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{y^2+4}x\implies\dfrac{2y}{y^2+4}\,\mathrm dy=\dfrac{\mathrm dx}{x\ln x}$

Integrate both sides; on the left, set $u=y^2+4$ so that $\mathrm du=2y\,\mathrm dy$ ; on the right, set $v=\ln x$ so that $\mathrm dv=\dfrac{\mathrm dx}x$ . Then

$\displaystyle\int\frac{2y}{y^2+4}\,\mathrm dy=\int\dfrac{\mathrm dx}{x\ln x}\iff\int\frac{\mathrm du}u=\int\dfrac{\mathrm dv}v$

$\implies\ln|u|=\ln|v|+C$

$\implies\ln(y^2+4)=\ln|\ln x|+C$

$\implies y^2+4=e^{\ln|\ln x|+C}$

$\implies y^2=C|\ln x|-4$

$\implies y=\pm\sqrt{C|\ln x|-4}$
