The Proof is given below.

Step-by-step explanation:

Given:

AB ≅ CD

∠BAC ≅ ∠ACD

To Prove:

ΔABC ≅ ΔCDA

Proof:

In  Δ ABC and Δ CDA

AB ≅ CD              .......……….{Given}

∠BAC ≅ ∠ACD    .....………..{Given}

AC ≅ AC              ......……….{Reflexive Property}

Δ ABC ≅ Δ CDA …...........{Side-Angle-Side test}

b.-4 units

all you   do is count how many times you move

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
