It doesn't have to be all skype. I have other platforms too that work well. I will do more showing via other platforms than talking. But skype is necessary.

Angle B is 76°
Angle ADB is 180°-76°-90° = 14°
Angle BDC is 180° - 128° = 25°

unklerhaukus · Answer

Length CD = √(16^2-9^2) = √175 = 5√7 ~ 13.2
Length AD / 16 = sin(76°) , Length AD = 16 sin (76°) ~ 9.1
Length BA / 16 = cos(76°) , Length AD = 16 cos(76°) ~ 13.2
