ΔABC ​~ ΔDEC. ∠1 and ∠2 have the same measure. Find DC and DE.​ (Hint: Let DC=x and AC=x+3. Use the figure shown.)
Sveta_85 [38]
DC/AC=EC/BC
x/(x+3)=10/16
10(x+3)=16x
10x+30=16x
30=6x
x=5
DC=x=5
DC=5 units long

10/16=DE/AB,     DE=y

10/16=y/10
16*y=10*10
y=6.25≈6.3
DE≈6.3

Doss [256]

Let the total number of workers be x

Workers earning minimum wages=24

24=15% of x

Therefore,x*15/100=24

Taking 100 to RHS,x*15=24*100

x=2400/15

=160
