We have that triangle RST and triangle NPQ are congruent, therefore m

We need to find first the value of x so we have the next equation


m\angle R=m\angle N
-7x+9=-10x
\begin{gathered} -7x+10x=-9 \\ 3x=-9 \\ x=(-9)/(3) \\ x=-3 \end{gathered}

Then we substitute the value


m\angle R=-7(-3)+9=30=m\angle N

ANSWER

m
