Right trapezoid

The right trapezoid has bases 3.2 cm and 62 mm long. The shorter leg has a length of 0.25 dm. Calculate the lengths of the diagonals and the second leg.

Correct answer:

u1 =  6.6851 cm
u2 =  4.0608 cm
b =  3.9051 cm

Step-by-step explanation:

a=62 mm cm=62:10  cm=6.2 cm c=3.2 cm d=0.25 dm cm=0.25 10  cm=2.5 cm  u12  = d2 + a2 u1=d2+a2=2.52+6.22=6.6851 cm
u22  = d2 + c2 u2=d2+c2=2.52+3.22=4.0608 cm
b2 = d2 + (ac)2 b=d2+(ac)2=2.52+(6.23.2)2=3.9051 cm
