Given triangle RST=NPQ , m 12 years ago

Answer 1

@morgansalmonPEACE

Angles R and N are corresponding angles of congruent triangles.

By definition of congruent triangles, angles R and N are congruent.

Answer 2

Congruent angles have the same measure.

So, solve this equation for x:

-7x+9 =-10x

Once you get x, remember to substitute that value into the algebraic expression for angles R and N to get the angle measures.
