Answer:
id.k if is a -1 in the beginning i think it’s 0 but i’m not sure so
Let x be the unknown angle.
We know that x+50=120 because the value of an exterior angle of a triangle is equal to the sum of the other 2 interior angles.
x+50 = 120
Subtract both sides by 50
x = 70
The value of the unknown angle is 70 degrees.
Have an awesome day! :)

Answer: Choice C</h3>
Explanation:
The x coordinates are the same, so we subtract the y coordinates
7-1 = 6
This shows the points have a distance of 6 units. You can plot the two points and count the numbers of spaces between them to confirm this.
So to fine slope you would use the formula down below:
rise/run
So use a graphed point, 0, -5 and you rise or count up quadrants up to a point and then horizontally move to when you find that point.
So from 0,-5 go up 9 vertically, and you would be on the 4
Go horizontal 3 spots and your on a designated point.
So the rise is four and the run is 3
So 4/3 is the slope
In the y= Mx + b equation you would set the equation like this:
y= 4/3 + -5
The m in this formula stands for the slop and the b stands for the y-intercept
The y-intercept is the point that is on the y-axis and where it starts.
Answer:
u1v1 + u2v2 + u3v3
Step-by-step explanation:
Inner product is a method of multiplying vectors, with the outcome being a scalar. \
u = (u1, u2, u3) and v = (v1, v2, v3)
Inner product = u.v = (u1, u2, u3). (v1, v2, v3)
= u1v1 + u2v2 + u3v3
