Answer:
m 1 = 45 degrees because 1 and the angle measuring 135 degrees are supplementary angles.
m 2 = 95 degrees because 2 and the angle measuring 95 degrees are vertical angles.
m 3 = 40 degrees because 1, 2, and 3 form a triangle
Step-by-step explanation:
Answer:
in this case you can use protector also but
there is another way
Step-by-step explanation:
as we know sum of a triangle is 180 degree
so let's D= 2x,x
35+x+2x=180
3x+35=180
3x=180-35
3x=145
x=145÷3
x =46.06
ion really care bout school but i still go
<h2>Option (c) angle 9 </h2><h2>Option (d) angle 12 </h2>
= x° = ∠9 as they are corresponding angles .
= ∠5 = x° = ∠12 because angle 12 and angle 9 are vertically opposite angles due to which their value is equal . Since angle 5 = angle 9 , x° will also be equal to angle 12 .
Answer:
The 2003 scores have a higher coefficient of variation, so they are more dispersed
Step-by-step explanation:
We have to find the coefficient of variation(CV) for both these tests.
In which 
is the mean and 
is the standard deviation.
Whoever has the higher CV has the higher variation, that is, is more dispersed.
2003
2004
The 2003 scores have a higher coefficient of variation, so they are more dispersed.
