Plane A leaves the airport. One hour later, Plane B leaves the same airport on the same course. It catches up to Plane A in h. The average speed of Plane B is 300 km/h faster than plane A. Find the speed of each plane.

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p

miss u!

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

the answer is 8.64

step-by-step explanation:

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.
