Answer 1

Answer:

take base as 2units and height as 1 units

Answer 2

Answer:

to find root x for any positive real number x we mark B so that AB is equals to X units and that BC is equals to 1 unit then we find BD is equals to root x

we can prove this result using the Pythagoras theorem

the radius of the circle is X + 1 upon 2 units

thereforeOC equals to ODis equals too ok equals to X + 1 upon 2 units

now OB is equals to x minus (x + 1 upon 2) is equals to x minus one upon two

so by Pythagoras theorem we have

BD square equals toOD square minus ob square equals to

X + 1 upon 2 ka whole square minus x minus 1 upon 2 ka whole square is equals to 4 X upon 4 is equals to X

this shows that BD is equals to root x

this is just the explanation of the question
