How do I find X thanks​

x = 60

Step-by-step explanation:

By applying mean ratio theorem in the given right triangles ΔABC and ΔBDC,

BD² = AD × DC

BD² = 36 × 64

BD =

BD = 48

By applying Pythagoras theorem in right triangle ΔADB,

AB² = AD² + BD²

x² = (48)² + (36)²

x² = 3600

x = 60

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i
