​

Answer 1

Although scholarly debate continues about the exact causes of the Revolution, the following reasons are commonly adduced: (1) the bourgeoisie resented its exclusion from political power and positions of honour; (2) the peasants were acutely aware of their situation and were less and less willing to support the ...

Answer 2

Answer:

i. ∆PQB and tPBC have same height PQ. A(∆PQB)/A(∆PBC)

= BQ/BC ...[Triangles having equal height]

ii. ∆PBC and ∆ABC have same base BC. A(∆PBC)/A(∆ABC) = PQ/AD ...[Triangles having equal base]

iii. ∆ABC and ∆ADC have same height AD. A(∆ABC)/A(∆ADC) = BC/DC ...[Triangles having equal heigh]

iv A(∆ADC)/A(∆PQC) = (DC x AD)/(QC x PQ) ...[Ratio of areas of two triangles is equal to the ratio of the product of their based and corresponding heights]
