Question

Help!!

In the given figure, ∆ABC is congruent to ∆XYZ, find the value of "a".​

Answer 1

Answer:

Step-by-step explanation:

Corresponding parts of congruent triangles are congruent.

So, XY = AB

3a - 3.9 = 1.7a - 1.3

3a          = 1.7a - 1.3 + 3.9

3a          = 1.7a + 2.6

3a -1.7a = 2.6

     1.3a = 2.6

         a = 2.6/1.3

a = 2

ΔABC ≅ ΔXYZ

First two letter

AB = XY

Second and third letters

BC = YZ

Third and first letter

CA = ZX
