In this problem, you are given a right-angled triangle.

Point L is the vertex of the right angle.

The leg LR due East is 5 miles long.

The hypotenuse AR is 7 miles long.


They want you find the length of the leg LA, which is due to North.


Use the Pythagorean formula

    LA =  =  =  miles.


To get the value, use your calculator.

Solved.
