The roads that connect three buildings form a right triangle. use the image to find the distance between the library and the museum.

The distance between library and museum is 400 yards.

Step-by-step explanation:

Let L represents the position of library, R represents the restaurant and M represents the museum,

Since, By the given diagram,

∠MLR = 90°,

LR = 300 yd,

RM = 500 yd,

So, by the Pythagoras theorem,

By substituting the values,

Hence, the distance between library and museum is 400 yards.

2nd one in the first row is correct
