Convert the angle \theta=\dfrac{257\pi}{360}θ= 360 257π theta, equals, start fraction, 257, pi, divided by, 360, end fraction radians to degrees. Express your answer exactly. \theta=θ=theta, equals ^\circ ∘

Step-by-step explanation:

The given angle measure is

We need to convert the radian measure to degree.

To convert radian to degree, multiply the given measure by .

On simplification, we get

Hence, the required measure is .

step-by-step explanation:

its 512 because parenthesis and to the 2nd power is 512 so it will be 512

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.
