The distance between city a and city b is 6.8cm. what is the actual distance if the map scale 2cm=40miles?

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
