The shorter leg of a 30°-60°-90° triangle measures 3 inches. what is the length of the longer leg?

For a 30°-60°-90° triangle, the sides will have a ratio of 1:sqrt(3):2. Therefore if the shortest side (across the 30° angle) has a length ratio of 1, then the longer leg has a length ratio of sqrt(3). Therefore we have the proportion:
3 inches/1 = x/sqrt(3)
x = 3sqrt(3) inches

Note that the side of length ratio 2 is the hypotenuse, not the longer leg.

Africans learned what the europeans wanted them to learn. instead of learning about african history and current information that could and would them they learned solely what europe wanted them to. and not everyone received the same education, some received better and others none.
