Answer:
The answer is 41
Step-by-step explanation:
1,3,4,6,10,5,9,20 and 7 :)
The distance between two points (x₁,y1),(x₂,y₂) is d

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>

= 3√2
The length of WX =

= 6
The length of WZ =

= 6
The length of XY = <span><span>

= 3√2
</span>The length of ZY = </span><span>

= 3√2
∴ WX = WZ ⇒⇒⇒ proved
XY = ZY ⇒⇒⇒ proved
WY = WY ⇒⇒⇒ reflexive property
∴ Δ</span><span>WYZ is congruent to ΔWYX by SSS method</span>
Answer:
find the midpoint of the line AB...
and plot it on the graph
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)
