Okay <em>we need to know the number of degrees in this shape first</em> in order to find x.
The formula to find the # of degrees in any polygon is
180 ( n - 2 )
n = the number of sides the figure has
This figure has 8 sides
180 ( 8 - 2 )
180 (6) = 1080°
This figure is 1080°
To find x, let's <u>subtract all the other degrees</u> they gave us
<em>1080° - 124° - 136° - 132° - 129° - 116° - 158° - 141° = 144°</em>
x = 144°
I hope I helped!
Answer:
The answer for this problem would be 50.
Step-by-step explanation:
If you calculate 90% of 50, you should get 45 so, the answer is 50.
Answer:
0.67
Step-by-step explanation:
z = (x-μ)/σ, where
x is the raw score = 5.6 seconds
μ is the population mean = 5.2 seconds
σ is the population standard deviation = 0.3 seconds
z = 5.6 - 5.2/0.3
z = 0.66667
z score is approximately 0.67
The z-score for a player who runs a time of 5.6 seconds is 0.67
Answer:
90
Step-by-step explanation:
30 divided 15 = 2
2 times 45 = 90
