After 5 years they will not be as tall each other.Ben will be 4 feet and 7.5
and Johnny will be 3 feet and 10.8.
Answer:
4
Step-by-step explanation:
with a 30-60-90 triangle the hypotenuse is 2x while the smaller 30 side is x. This means that LJ is 4
. Then for a 45-45-90 the hypotenuse is
compared to a leg being X. So you remove the
leaving you with 4
AB=AC
AD=AD –-----> ABD≈CAD
BD=DC
BA=AC
A1=A2 -------->BAE≈CAE
AE=AE
BD=DC
D1=D2 -------->BDE≈CDE
DE=DE
so if BDE≈CDE AE and BC are perpendicular.
hope this helps
