Answer:

∠AEC = 139°

Step-by-step explanation:

Since EC bisects ∠BED then ∠BEC = ∠CED = 4x + 1

∠AED = ∠AEB + ∠BEC + ∠CED = 180 ← straight angle

Substitute values into the equation

11x - 12 + 4x + 1 + 4x + 1 = 180, that is

19x - 10 = 180 ( add 10 to both sides )

19x = 190 ( divide both sides by 19 )

x = 10

Hence

∠AEC = ∠AEB + ∠BEC = 11x - 12 + 4x + 1 = 15x - 11, hence

∠AEC = (15 × 10) - 11 = 150 - 11 = 139°

H(x) = x^3 - 2x g(x) = 3x + 4 Find (h+g)(4)

pashok25 [27]

9514 1404 393

Answer:

Step-by-step explanation:

h(4) = 4^3 -2·4 = 64 -8 = 56

g(4) = 3·4 +4 = 16

Then the sum is ...

(h+g)(4) = h(4) + g(4) = 56 +16

(h+g)(4) = 72
