Given: In triangle HIJ and triangle MNO we have

here, HI and NN are the included side between ∠I & ∠H and ∠N and ∠O.
So , by ASA congruence rule,
ΔHIJ ≅ ΔMNO
So by CPCTC (corresponding parts of the congruent triangles are congruent)

Answer:
-1 1/9
Step-by-step explanation:
2x + 7x = -10 (equation)
9x = -10 (combine like terms)
x = -10/9 (move the 9 over)
x = -1 1/9 (simplify)
