Q:
# ΔABC ~ ΔDEC. ∠1 and ∠2 have the same measure. Find DC and. DE (Hint: Let DC = x and AC =x+66.)Use the figure shown.DC is ___ unit(s) long.(Round to the nearest tenth as needed.)

Accepted Solution

A:

x : 20 = x+6 : 30

30x = 20x + 120

10x = 120

x = 12

DC is 12 units long

30x = 20x + 120

10x = 120

x = 12

DC is 12 units long
