Using similar triangles, we can set up the following proportion:
AC/AD = DC/BD
Substitute the given values:
5/AD = 5/15
Solve for AD:
5AD = 75
AD = 75/5
AD = 15
Therefore, the length of line AD is 15.
Given right triangle A, B, CABC with altitude start overline, B, D, end overline
BD
drawn to hypotenuse start overline, A, C, end overline
AC
. If B, D, equals, 15BD=15 and D, C, equals, 5, commaDC=5, what is the length of start overline, A, D, end overline, question mark
AD
?
