1. Elsa is designing a commercial jet. She drew a model of her design using the scale shown below.
According to her design, what will be the length and width, in feet, of the actual det?
1 in = 6 ft
Model: 771-196AZ
Length
35 5 in
Width
40.5 in-

2 is the final ! : )

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.
