The figure shows five locations in a city. The road which connects the playground and the pharmacy is parallel to the road which connects the school with the ice-cream shop, as shown. What is the distance between the town hall and the pharmacy? 1.5 miles 2.0 miles 4.5 miles 3.0 miles
It's 2 miles!
Apply the parallel property, the angle of playground and school are equal! => the distance from pharmacy to icream shop: x = sqrt (12) * tan30 = 2 mi
Oop! forgot to add 2 + 2 = 4 mi
whats the answer abayomil12?
To get to the answer, you will need to calculate the angle between Townhall-playground and Townhall-Pharmacy using the cosine function in the following page: http://en.wikipedia.org/wiki/Trigonometry Then use the cosine function and calculated angle to obtain the distance between Townhall and Pharmacy.
