Question

The picture shows a portion of an irrigation system for a farm. LM is the main water pipe. What is the length of the main water pipe LM? 19.1 feet 12.7 feet 5.5 feet 6.4 feet

Answer 1

This is a classic example of a 30, 60, 90 degree triangle :)
the sides in across from each angle are as follows:
30- x
60- x*sqrt(3)
90- 2x

so you have the side across from the 60 degree angle, correct? using that, try to figure out what the value of x is, and then multiply it by 2 and you have your answer! :)

Answer 2

would x be 11?

Answer 3

nope. x*sqrt(3) = 11

Answer 4

im confused, whats x?

Answer 5

x is the value of the side across from the 30 degree angle, so line KL in this case. and LM is equal to 2*x

Answer 6

im so confused :(
