iv) If angle BAC = x¬į, write down the size of angle ACD in terms of x. Give reasons.
If angle BCA = y¬į, write down the size of angle CAD in terms of y. Hence, prove that AADC is congruent to ACBA Hence, prove that AB = DC. The Ô¨Ārst term of an AP (arithmetic progression) is -64. The common difference is 5. i)
