Please help with this question! I am desperate!

Answer 1

Answer:

So the 2nd option is the correct option.

Step-by-step explanation:

U and V have the same y-coordinate.  The distance between them is just the difference between the x-coordinates:

UV = 2 - (-2) = 2 + 2 = 4

This rules out 3rd and 4th options.

No point checking VW as this is the same in 1st and 2nd options anyway.

Both 1st and 2nd options say ∠V is a right angle, so this must be true (no need to check it).

By Pythagoras' Theorem:

UW² = UV² + VW² = 4² + 7² = 16 + 49 = 65

=> UW = √65, which is a bit more than 8  (since 8² = 64).

So the 2nd option is the correct option.

Answer 2

option 2 is correct

Uv=4
