There are three elements in that set.
Answer:
combine -3-1

if you want to solve for x then you would move the -14 to the left buy adding 14 to both sides.

your equation there will be

then you will divide -2 on both sides

finally x will equal

Answer:
Nice handwriting!
Step-by-step explanation:
I have no idea im only in 8th grade.
Answer:
Step-by-step explanation:
There are two case I used, since we are not give diagram, so I assumed that U can be the right angle and also assume that W can be the right angle so, I used both assumption to solve, check attachment
1. Using Trigonometry
Assuming that U is the right angle
Tan θ = opp / adj
Tan 60 = UW / UV
Tan 60 = UW / 18
UW = 18 × Tan60
UW = 18 × √3
UW = 18√3
UW = 31.18 unit
Also, assume that W is right angle
Using trigonometry
Sinθ = opp / hyp
Sin60 = UW / UV
Sin60 = UW / 18
UW = 18 × sin60
UW = 18 × √3/2
UW = 9√3
UW = 15.59 unit
Answer:
720
Step-by-step explanation:
Since there are six coordinates, the polygon must be a hexagon.
Sum of angles in a polygon= (n-2)×180
= (6-2) × 180
= 720
