See diagram. You can see a general quadrilateral with AB || DC and AD = BC.

Extend the sides AD and BC till E and F as shown.

As AB and CD are two parallel lines and AD intersects them both, the angles D and EAB are same. But angle EAB = 180 - A. so, angleD = 180 - A

Similarly, the line BC intersects parallel lines AB and DC, so angle C = angle FBA = 180 - B

Now, draw perpendiculars from D and C onto AB meeting AB at G and H respectively. Since AB || DC, the sides DG || CH. Also, DG = CH = distance between the parallel lines.

Looking at the triangles DGA and CHB, we find that DG = CH, AD = BC (given), angle G = angle H = 90°.ΔDGA andΔCHB are congruent. Hence angleA = angleB.

2In quadrilateral PSQR,

SP || QR (SP is a part of DP and QR is a part of QB)

Similarly, SQ || PR

So, PSQR is a parallelogram

We know, a number is only divisible by 11 if the difference between its sum of odd digits and even digits is 0 or 11.Here 99 digits is a odd number. So we will assume a number whose digits count is odd. for example: 2xxx2Let x=1 > 21112 => 2+1+2-1+1 = 3x=2 > 22222 = 2+2+2-2+2 = 2x=3 > 23332 = 2+3+2-3+3 = 1x=4 > 24442 = 2+4+2-4+4 = 0Therefore, 4 is the answer

we have x² -2x + 1 = 0so, (x-1)² = 0So, x = 1x + 1/x = 1 + 1 = 2

To explain the outcome of WWI economic historians stress the increasingly mechanised nature of warfare, waged for years on end by massed forces. They emphasise things like numbers of tanks, guns, ships, airplanes and ammunition, or aggregate indices of munitions production. Military historians object that this leaves no room for factors such as leadership, discipline, heroism, or villainy.

The opposition between cold figures and hot blood is to some extent false. Leadership and psychology clearly did matter, but less so than in previous eras. In WWI, multi-million man armies took the field and remained there for years, giving and taking appalling losses without disintegrating. In these circumstances of ‘total war’, numbers of men and the volume of supplies played the decisive role (Chickering and Förster 2000).

WORLD WAR 2

Many men went to fight – women did their work. This had a long-term effect upon women's lib, although any gains seemed to evaporate straight after the war, when the men came back and many women went back to the kitchen. However, many of the leaders of women's lib in the 1860s had begun their working careers during the war.

There was a huge growth in munitions/ aircraft industries – other industries (eg house building) were put on hold

There was a huge emphasis on food production – Dig for Victory

rationing – notably of petrol

Shortages of workers – schedule of Protected Occupations prevented the call-up of key workers to the armed services, and the Essential Works Order (1941) allowed the government to conscript people to certain work.Of course, after the war, all the men came home and this created further employment disruption.

The Government had to take control of the economy – eg who worked where, trade, railways, shipping, banking etc.

MASSIVE government debts were accumulated, particularly toAmerica(remember Lend-lease)

Many men (including COs) were sent to work in the mines

Huge losses of merchant shipping to submarines

Destruction of factories/machines – in 1945BritainLOST 12% of her productive capacity
