In a parallelogram, adjacent angles make 180°

So in 22

11x + 11 + 70 = 180
11x = 99
x = 9

In 23

12x + 10 + 50 = 180
12x = 120
x = 10

I need help on how to solve this so anything is good :)

DanielleElmas [232]

Answer:

STUV is a square

Step-by-step explanation:

segment length² = (x-x₁)² + (y-y₁)²

ST²: (-9 - 1)2 + (14 - 10)² = (-10)² + 4² = 116 (the rest follow this formula)

TU² = 116 TV² = 232 SU² = 232 SV² = 116 UV² = 116

ST = TU =SV = UV (4 sides congruent)

TV = SU (diagonal equal)

This is a square
