Question

2. Given ARST = ANPO. IZR=-7x + 9. m N=-10x, find mZR and mZN. (1 point) 30 660 40 50

Answer 1

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=\frac{-9}{3} \\ x=-3 \end{gathered}$

Then we substitute the value

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

ANSWER

m
