-----> substitute in equation A
Your Answer:
what type of question is this?
Answer:
The number of lines for each angle tell you which angles are congruent.
The angle with one line in one triangle is the same as the angle with one line in the other triangle.
(a)
∠A ≅ ∠X
∠B ≅ ∠Z
∠C ≅ ∠Y
The dashes of the side lengths tell you which side lengths are congruent.
The line with one dash in one triangle is the same as the line with one dash in the other triangle.
(b)
AB ≅ XZ
AC ≅ XY
BC ≅ ZY
(c)
ΔBCA ≅ ΔZYX
