2x+ x =180 degree( being co interior angle)
3x =180
x=180/3
x=60 degree
Here ,
Angle BCD=2x
=2*60
=120 degree

BCD= 120 degrees. explanation: the 4 angles of a parallelogram must equal 360 degrees. so you add all 4 angles & get 6x. you then take that 6 & divide it from 360 (360/6) and get 60. therefore x=60. so then you just multiple BCD (2x) by 60 and you get 120 degrees

0.5 cm on a map represent 3 Km in the actual

using proportion

Find out the actual distance between the towns, if the distance on the map is 12.5 cm

$\frac{0.5}{3}\ \frac{cm}{km}=\frac{12.5}{x}\ \frac{cm}{km}\\\\x=3(12.5)/0.5\\\\x=75\ km$
