Answer:
Y= -8
X= 3
Step-by-step explanation:
apply -(-a)=a rule
-23+4*8/3
-23+4*8=9
9/3
=3
2y-(3)=-19
y= -8
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:
D.252
Step-by-step explanation:
In this question, We have to find which rotation about its center will carry a regular decagon onto itself?
A decagon : 10 sided polygon
As we know, a full rotation can be 360°.
For a decagon: 360/10 =36
For a decagon, any multiple of 36 can map onto itself.
In our options only 252 is the multiple of 36.
So, correct answer is option D 252
