What is the missing step in this proof? A. ∠CAB ≅ ∠ACB, ∠EDB ≅ ∠DEB

B. ∠ADE ≅ ∠DBE, ∠CED ≅ ∠EBD

C. ∠CAD ≅ ∠ACE, ∠ADE ≅ ∠CED

D. ∠CAB ≅ ∠EDB, ∠ACB ≅ ∠DEB

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

its adding 5.5 each time

step-by-step explanation:

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)

$450 i think. hope this ☺
