Question

ADvanced Geometry Question.... I need to find the angle CED, but the problem's image is a 3D depiction. I can't seem to figure out how to get the needed sides. I know what the answer is, but I don't know how to get it. Plz help. I posted the pic

Answer 1

let Z intersect DC in F

than will get FE like altitude in triangle DCE

note FE = x so than FB= x+2

consider the right triangle FAB

FA = 5 ft
AB = 10 ft
FB = x +2 ft

writing for these pythagora will get

FB^2 = 100 +25

FB = sqr125 = 11,18 ft

so than FE = 11,18 - 2 = 9,18 ft
ide divide aja
FE bisect angle E in E_1 and E_2

so than writing tan E_1 = opposite side divide adjacent side

so this mean tan E_1 = 4/9,18 = 0,43

so E_1 = arctan 0,43

E_2 = arctan 0,43

angle E = <E_1 +<E_2

so like an idea to solve it hope this will help you

good luck

ty @ParthKohli appreciate your ,,medal" --- thank you !

Answer 3

your answer is so appreciated, trouble is, I don't understand what you wrote. It may be clear to you, but not to me. I need the explanation in everyday language, not mathspeak. If I understood that, I probably wouldn't have the question. I do so much appreciate you taking time to answer, but I just don't understand what you said.
