<em>AC bisects ∠BAD, => ∠BAC=∠CAD ..... (1)</em>
<em>thus in ΔABC and ΔADC, ∠ABC=∠ADC (given), </em>
<em> ∠BAC=∠CAD [from (1)],</em>
<em>AC (opposite side side of ∠ABC) = AC (opposite side side of ∠ADC), the common side between ΔABC and ΔADC</em>
<em>Hence, by AAS axiom, ΔABC ≅ ΔADC,</em>
<em>Therefore, BC (opposite side side of ∠BAC) = DC (opposite side side of ∠CAD), since (1)</em>
<em />
Hence, BC=DC proved.

Addition and subtraction
Answer:
R = 3.6
A = 2
Step-by-step explanation:
R is inversely proportional to A
....which means that....
; R = k/A.....(where k is a constant that does not change)....
;If R = 12 and A = 1.5....then k = 18..
obtain k,by substituting the values into the equation...k = RA
a) If A = 5....then R = 18/5....
; Ans..., R = 3.6
b) If R = 9....then A = 18/9
;Ans..., A = 2
