Answer:

m<BCD is 62 degrees

Step-by-step explanation:

From the diagram given, both triangles are similar triangles and triangle CAB is isosceles in nature;

Hence;

m<CAB = m<CBA

Also

m<CAB + m<CBA = m<BCD

31 + 31 = m<BCD

Swap

m<BCD = 31 + 31

m<BCD = 62 degrees

hence the measure of m<BCD is 62 degrees

Find the distance between the pair of parallel lines, y = x-11 & y = x-7

kenny6666 [7]

$k:\ y = x-11\ \ \ \Leftrightarrow\ \ \ x-y-11=0\\ and\\ l:\ y = x-7\ \ \ \Leftrightarrow\ \ \ x-y-7=0\\\\the\ distance:\\\\ d(k;l)= \frac{\big{|-11-(-7)|}}{\big{ \sqrt{1^2+1^2} }} =\frac{\big{|-11+7|}}{\big{ \sqrt{2} }} =\frac{\big{|-4|}}{\big{ \sqrt{2} }} =\frac{\big{4\cdot \sqrt{2} }}{\big{ \sqrt{2}\cdot \sqrt{2} }} =\frac{\big{4 \sqrt{2} }}{\big{2 }} =2 \sqrt{2}$
