Brynn and denise launch their rockets at the same time. the height of brynn’s rocket, in meters, is given by the function f(x)=−4.9 x 2 +75x , where x is the number of seconds after the launch. the height of denise’s rocket, in meters, is given by the function g(x)=−4.9 x 2 +50x+38 , where x is the number of seconds after the launch. there is a moment when the rockets are at the same height. what is this height? enter your answer, rounded to the nearest tenth of a meter, in the box

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

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.
