In rectangle ABCD, M is the midpoint of CD, AC=73 and AM=5 .
What is the perimeter of ABCD ?

Which equation represents the model shown? a)1/3 divide 1/6 = 2 b)2/3 divide 1/6 = 2/18 c)1/3 divide 1/6 = 1/18 d)2/3 divide 1/6 =4

Lena reflected this figure across the x-axis. she writes the vertices of the image as a'(−2, 8), b'(−5, 6), c'(−8, 8), d'(−4, 2).

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?
