Answer:

x = 20

Step-by-step explanation:

If two lines are cut by a transversal and the corresponding angles are congruent, the lines are parallel.

\rm \longrightarrow \angle 2 =  \angle 5 \\  \\  \rm \longrightarrow 3x - 20 = x + 20 \\ \\ \rm Add \ 20 \ both \ sides:  \\  \rm \longrightarrow 3x - 20 + 20 = x + 20 + 20 \\  \\  \rm \longrightarrow 3x = x + 40 \\ \\ \rm Substrate \ x \ from \ both \ sides:  \\  \rm \longrightarrow 3x - x = x - x + 40 \\  \\  \rm \longrightarrow 2x = 40 \\ \\ \rm Divide \ both \ sides \ by \ 2: \\  \rm \longrightarrow  \frac{ \cancel{2}x }{ \cancel{2}}  =  \dfrac{40}{2}  \\  \\  \rm \longrightarrow x = 20

Hello from MrBillDoesMath!

Answer:

The fourth choice,  b = +\- sqrt( sg + a^2)

Discussion:

s = (b^2 - a^2)/g     =>              multiply both sides by "g"

sg = b^2 - a^2        =>               add a^2 to both sides

sg + a^2 = b^2       =>                take the square root of each side

b = +\- sqrt( sg + a^2)


which is the fourth choice.


Thank you,

MrB
