Answer:
x=35
Step-by-step explanation:
So the line XYZ is 180. The angles together should equal 180 in total.
The equation would be (2x-5) + (3x+10) = 180.
2x-5+3x+10=180
You want to combine like terms.
2x+3x and -5+10
5x+5=180
subtract 5 from both sides. Need variable alone.
5x+5(-5)=180(-5)
5-5 is 0 and 180-5 is 175
5x=175
Divide by 5 on both sides.
5x/5=175/5
x=35
The coordinate is (-1/2, √3/2) and the missing values will be 2 and 3 if the angle is 120 degree.
<h3>What is the polar equation?</h3>
A polar coordinate system is a two-dimensional coordinate system in which a distance from a reference point and an angle from a reference direction identify each point on a plane.
We have an angle of 120 degree
θ = 120 degree
r = 1 unit
As we know, the coordinate in the polar form from the rectangular form is:
x = rcosθ = cos120 = -1/2
y = rsinθ = sin120 = √3/2
Thus, the coordinate is (-1/2, √3/2) and the missing values will be 2 and 3 if the angle is 120 degree.

Answer:
Yes, it is proportional.
You know because if you do $9/3 lbs that = 9/3 = $3 per pound
and
if you do $1.50/0.5 lbs = 1.5/0.5 = $3 per pound
Both of them are $3 per pound, so it is proportional.
