Answer:
the last answer
Step-by-step explanation:
-(-2x-6y=-16)
2x+6y=16
4x-6y=-58
Y's cancel out, then add the rest
6x=-42
divide both sides by six
x=-7
plug x into any previous equation
2(-7)+6y=16
-14+6y=16
6y=30
y=5
Step-by-step explanation:
GI = GI (common)
GJ=HI(given)
GH = JI(given)
so triangle GJL and triangle GHI are congruent by S.S.S axiom,
<J=<H (corresponding angle of congruent triangles are equal)
