The triangles are congruent, which sequence of motions will take triangle XYZ onto triangle BCA? 1: Translate XYZ along vector YC. Rotate X'Y'Z' around C by angle BCX'. Reflect X"Y"Z" over CB.

2: Translate XYZ along vector YC. Rotate X'Y'Z'around C by angle BCX Reflect X"Y"Z" over AC.

3:Translate XYZ along vector YC. Rotate X'YZ' around C by angle X'YA. Reflect X"Y"Z" over CB.

4: Translate XYZ along vector YC. Rotate X'Y'Z' around C by angle X'Y'A. Reflect X"Y"Z" over AC.​

3: အားနည်းချက်ကို YC တလျှောက်တွင် XYZ Translate ။ ထောင့် X'YA ဖြင့် C ပတ်လည် X'YZ ကိုလှည့်ပါ။ CB ရှိ“ X” Y“ Z” ကိုရောင်ပြန်ဟပ်ပါ။

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
