50 since a triangle has to equal 180, trust!
Yes it is a geometric sequence and the common ratio is 2/3
Ten to the <span>negative second power L over one cL is the one among the following choices that is a possible equivalence that can be used in a conversion. The correct option among all the options that are given in the question is the third option or option "C". I hope the answer helps you.</span>
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>
