Karla is drawing a portrait of her sister. Karla wants to make sure she draws the face with the right proportions. In reality, her sister’s eyes are 1.2 inches apart (from pupil to pupil) and her mouth is 1.8 inches above the bottom of her chin. Karla has already drawn her sister’s eyes 0.4 inches apart on the paper. How far above the bottom of the chin must Karla draw her mouth?

me! what did you put for this question?

step-by-step explanation:

i need a diagram

step-by-step explanation:

no

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.

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
