Answer:
m<A = 20
Step-by-step explanation:
6y plus 3y = 9y
180 divided by 9 = 20
20x6=120
20x2=40
120+40=160
a triangle is equal to 180 so..
180-160=20
i did 6y + 3y because that line is 180 degrees ( half of a circle)
<h3>
Answer: Choice A) -10.73</h3>
Work Shown:
Plug x = 4.3 into the equation given
ŷ = 2.6 − 3.1x
ŷ = 2.6 − 3.1(4.3)
ŷ = 2.6 − 13.33
ŷ = -10.73
Note: The symbol ŷ is read as "y hat". It's used to estimate the y value when it comes to regression equations.
Answer:
Option A is correct.

The length opposite the angle is the vertical distance from the x-axis on the graph
Step-by-step explanation:
Given:
Unit circle is a circle centered at the origin, (0,0) with radius(r) i.,e r= 1.
The angle
forms an arc of length S and the x-axis and y-axis divide the coordinate plane and the unit circle as it is centered at (0.0).
Also, the terminal side intersect the circle at (x, y).
Now, to find the value of
,we will use the trigonometric ratios formulas :
For any right angle,
Here, hypotenuse = r =1 and the side opposite the angle
is also called the vertical distance from the x-axis.
therefore, 
Also, the length opposite the angle is the vertical distance from the x-axis on the graph
