Question

ABCD is a rectangle. Its diagonals meet at O.Find AC, if OA=3x +5 and OB =2x + 9.

Answer 1

see this answer which is mentioned above. answer is 34.i hope it will help you

Answer 2

since we know that,
the diagonals of a rectangle bisect each other;
therefore,
3x+5 = 2x + 9
x =4
therfore,
OA= 3(4) + 5
OA=17
THEREFORE,
AC=2(OA)
AC=2(17)
AC=34 units
