Find x y and ABHG for brainliest

because AB//EF//CD, using thales theorem in ABEF, we have:

we also have: CD//EF//GH => using thales theorem in CDGH:

with y = 26.25 => AB = 26.25 - 14 = 12.25

        x = 8 => GH = 5.8 - 3 = 40 - 3 = 37

+) the perimeter of ABHG = AB + AC + CE + GE + GH + HF + DF + BD

= 12.25 + 12 + 21 + 8 + 37 + 10 + 26.25 + 15

= 141.5

Step-by-step explanation:

b

step-by-step explanation:

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
