The measure of ∠DCB is 128°.

The measure of ∠ECD is 52°

Step-by-step explanation:

∠ACB + ∠ACE = 180°

(x+11)° + (3x+5)° = 180

⇒ 4x+16 = 180

⇒ 4x = 164

⇒ x = 164/4

x = 41°

∠DCB = ∠ACE ⇒ (3x+5)°

∠DCB = 3(41)+5 = 128°

∠ECD =∠ACB ⇒ (x+11)°

∠ECD = 41+11 = 52°

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
