Answer:
4)x=15
5)137 degrees
6)supplementary
7)complentary
8)neither
Step-by-step explanation:
4) complementary angles sum = 90
so (3*15+30)
45+30=75
angle 1+angle 2=90
angle 1+75=90
90-75=15
angle1=15
5) angle z is a linear angle which means angle43+anglez=180
180-43=137 degrees
6) supplementary angles =180 degrees
53+127=180
so these angles are supplementary
7) complementary angles =90
56+34=90
so these angles are complementary
8) angles are vertical
HOpe this helps plz vote my answer the brainiest if it does!!!
Finding the mean is you have to add it all up:
49+55+52+46+47+42+38= 328
The divide it by the amount of numbers so, 329/7= 47.
Subtract 47 from every number then, but even if you get a negative number you gotta keep it a positive so just ignore it if you get a negative answer when subtracting, once you do that you would add up those answers you got so;
2+8+5+1+0+5+9= 30
Then divide it again, 30/7
Which then you get the M.A.D which is 4.3, rounded to the nearest ten.
Answer:
5
Step-by-step explanation:
To evaluate (g ￮ h)(9), evaluate h(9) , then use this value to evaluate g(x)
h(9) = 
= 3, then
g(3) = 2(3) - 1 = 6 - 1 = 5
Answer:
Step-by-step explanation:
Given
f(x) = 
Finding f(-1) means, we have to put -1 in the places of x in the function,
So, putting x=-1 in the function
As the power 3 is odd, the minus will remain the same, while in the 2nd term minus will be eliminated due to even power. So,
=> 
=> 1
Hence,
