P(0,0) , Q(a+c,0)
R(2a+c,b) , S(a, b)
now apply distance formula to prove that opposite sides are congruent
OpenStudy (anonymous):
so 29 is c
OpenStudy (anonymous):
square root((x2 - x1)^2 +(y2 - y1)^2)
(for points P & Q)
square root((a+c - 0)^2 + (0-0)^2) => sq root((a+c)^2)
(for points RS)
square root((2a+c - a)^2 + (b-b)^2) => sq root((a+c)^2)
hence answer for question 1 is C
OpenStudy (anonymous):
Hey I was solving the first one :P

yes :)
OpenStudy (anonymous):
haha its okay
OpenStudy (anonymous):
2x - 5 = 5y + 2
x+3 = 3 y
2x - 5y = 7
x - 3y = -3
x= 36
y=13
