Hypotenuse=x
x2=(6)2+(8)2
x2=36+64 m2
x2=100m2
x=10 m
In the first 100 pages there are 10 pages with numbers 40-49 ( that is total of 11 4's) and another 4 in the units, 10's , 20's, .... 90's ( not including 40's) That is total of 9 4's.
So in first 100 pages there are 20 4's.
therefore there are 20 4's on pages 101-200 and another 20 4's on pages 201-300.
On pages 301 to 352 there are 15 4's.
answer is 3*20 + 15 = 75.
(n-2)*180=Sum of angle
(n-2)*180=2520
(n-2)=2520/180
n=14+2
n=16
49=16+x^2
x^2= 33
x= square root of 33
Not similar, since the ratio of corespondent side is not constant
suppose ∆PRQ ~ ∆MRN, then RN/RP = RM/RQ but the reality contradict
