Answer:
-Triangle RST is congruent to Triangle QST by SSS.
Step-by-step explanation:
-Since the questions state RST first, you must look at the other triangle in the same way. So therefore giving you triangle QST. Next we know that the sides of both triangles are congruent, giving you the anger to be SSS.
Answer:
2x+y=8
3x+y=-2
Elimination method
subtract equation (1) from (2)
1x/1=6/1
x=6
Substitute for y in equatw (1)
2 ×6+y=8
12+y=8
Collect like terms
y=8-12=-4
