W(1,8),X(7,8),Y(4,5), and Z(1,2) select all methods you can use to prove WYZ is congruent to WYX
marin [14]
The distance between two points (x₁,y1),(x₂,y₂) is d
d= \sqrt{(x2-x1)^2 + (y2-y1)^2}

For the given problem we have
<span>W(1,8),X(7,8),Y(4,5), and Z(1,2)

The length of WY = </span>\sqrt{(4-1)^2 + (5-8)^2} = 3√2
The length of WX = \sqrt{(7-1)^2 + (8-8)^2} = 6
The length of WZ = \sqrt{(1-1)^2 + (2-8)^2} = 6
The length of XY = <span><span>\sqrt{(4-7)^2 + (5-8)^2} = 3√2
</span>The length of ZY = </span><span>\sqrt{(1-4)^2 + (2-5)^2} = 3√2

∴ WX = WZ  ⇒⇒⇒ proved
    XY = ZY   ⇒⇒⇒ proved
    WY = WY  ⇒⇒⇒ reflexive property

∴ Δ</span><span>WYZ is congruent to ΔWYX by SSS method</span>

A curve is given by the parametric equations x = cos 2t * a * n * d * y = sin t , then the cartesian equation of the curve is gi
Dafna11 [192]

Answer:

Y² = (1-X) / 2

Step-by-step explanation:

According To The Question, We Have

X= Cos2t  &   Y= Sint

the cartesian equation of the curve is given by Y² = (1-X) / 2 .

Proof, Put The Value of X & Y in Cartesian Equation, We get

Sin²t = {1-(1-2×Sin²t)} / 2         [∴ Cos2t = 1 - 2×Sin²t]

Taking R.H.S

  • (1-1+2×Sin²t)/2
  • 2Sin²t/2   ⇔   Sin²t = L.H.S (Hence Proved)
