Question

There is no war in Ba Sing Se.

Answer 1

Part 1: Prove the triangles are similar.
Part 2: Determine the height of the house.

Answer 2

The triangles are similar by AA similarity

Answer 3

\[\frac{ 20 }{ 5 } = \frac{ x }{ 4 }\] so then cross mulitply

Answer 4

Do you notice that both the triangles are right angled?

Answer 5

2 angles of one triangle are congruent to 2 angles of the second triangle.

Answer 6

Correct they are Right angled.

Answer 7

Yes o:

Answer 8

So would that be Corresponding Angles I guess?

Answer 9

Thats kinda a hint if you want it to be. :)

Answer 10

once u cross multiply u get 5x = 80, then solve it to the height

Answer 11

They are perpendicular. so whats the distance?

Answer 12

Wait I think I read It wrong sorry.

Answer 13

Maybe not. :/

Answer 14

So I'll just name the triangle ABC and the right one DEF. So I have:

∠C = E Given
∠A = F Corresponding Angles Theorem
ΔABC = Δ DEF AA Postulate

Is this good so far?

Answer 15

C and E being the connected angles and A and F being the right angles.
