Answer:


\boxed {x = 4}


\boxed {\angle 1 = 41\textdegree}


\boxed {\angle 2 = 139\textdegree}


\boxed {\angle 3 = 41\textdegree}


\boxed {\angle 4 = 139\textdegree}

Explanation:

Both
\angle 1 and
\angle 3 are Vertical Angles. So, to the find actual measurement both of angles, you need to write an expression by using the following measurements labeled on both
\angle 1 and
\angle 3, and solve for
x:


\angle 1 = 8x + 9


\angle 3 = 14x - 15


8x + 9 = 14x - 15

-Solve:


8x + 9 = 14x - 15


8x + 9 - 14x = 14x - 14x - 15


-6x + 9 = -15


-6x + 9 = -15 - 9


-6x = -24


(-6x)/(-6) = (-24)/(-6)


\boxed {x = 4}

After you have the value of
x, use it to find the actual measurement of
\angle 1and
\angle 3:

-The value of
x:


x = 4

-Finding the measurement of
\angle 1:


8x + 9


8(4) + 9


32 + 9


41


\boxed {\angle 1 = 41\textdegree}

-Finding the measurement of
\angle 3:


14x - 15


14(4) - 15


56 - 15


41


\boxed {\angle 3 = 41\textdegree}

After you have the actual measurements of
\angle 1 and
\angle 3, find the actual measurements of
\angle 2 and
\angle 4.
\angle 1 and
\angle 2 are both supplementary (two angle that add up to
180\textdegree), you need to find the measurement of
\angle 2 by subtracting the measurement of
\angle 1 from
180\textdegree. Same thing for
\angle 3 and
\angle 4:

-Finding the measurement of
\angle 2:


180\textdegree - \angle 1


180\textdegree - 41\textdegree


139\textdegree


\boxed {\angle 2 = 139\textdegree}

-Finding the measurement of
\angle 4:


180\textdegree - \angle 3


180\textdegree - 41\textdegree


139\textdegree


\boxed {\angle 4 = 139\textdegree}

And were done.
