Question 78758
sqrt49/100=7/10 or .7 or 70% it is very rational.
------------------------------------------------------------
60^2+80^2=x^2
3600+6400=x62
10000=x^2
x=sqrt10000
x=100 answer. length of the diagonal.
------------------------------------------------------------
4^2+x^2=11^2
16+x^2=121
x^2=121-16
x^2=105
x=sqrt105
x=10.25 answer for the height up the wall for this ladder.
-------------------------------------------------------------
the distance between these two points is the diagonal formed by the right triangle with dimentions of:
x=(1+3)=4 & y=4+2)=6 thus usuing the pythagorean theorem a^2+b^2=c^2
4^2+6^2=c^2
16+36=c^2
c^2=52
c=sqrt52
c=7.2111 answer.
