Answer:
To write a linear equation in standard form, move each variable term to the left side of the equation and simplify.
A
x
+
B
y
=
C
Since
x
is on the right side of the equation, switch the sides so it is on the left side of the equation.

=
y
Move
y
to the left side of the equation because it contains a variable.

−
y

0
Move
2
to the right side of the equation because it does not contain a variable.

Step-by-step explanation:
B = (R+2)
3R = 2B
3R = 2(R+2)
3R = 2R + 4
3R-2R = 4
R= 4
B = R + 2, so B = 6
Angle 10 is 140 degrees
Angle 2 = Angle 10 = 140 degrees (Vertically Opposite Angles)
Angle 5 + Angle 4 = Angle 2 (Corresponding Angles)
Angle 5 + Angle 4 = 140
90 + Angle 4 = 140 (Angle 5 is 90 degrees because c is perpendicular to d)
Angle 4 = 50
