Question

Please help! I need to find the missing side to this shape. (file attached)

Answer 1

Draw a line parallel to distance between two buildings

then we get triangle in which side are

Hypotenuse=15

opposite=20-8

=12

adjacent=?

by Pythagoras,

(hypotenuse)²=(Opposite)²+(adjacent)²

15²=12²+adj²

225-144=adj²

81=adj²

9=adjacent

so the distance between two buildings is 9ft
