I have attached a diagram of the triangle described.
We can use any of the trigonometric functions to find angle x. Remember, SOH CAH TOA. And since we're finding the angle, we'll need to use an inverse trigonometric function. For this problem, I'll be using the sine function.
sin(x) = 84 / 85
x = sin^-1(84/85)
x = 81.2026 degrees (feel free to round to however many places you need)
Hope this helps!! :)
It only have 2 sides hope it helps you
13, 21, 34 are the next three numbers
The mean of x is 1.8 and standard deviation of X is 0.98 using calculations for mean and standard deviation by given values or data.
What is mean and standard deviation?
The standard deviation is a summary measure of the differences of each observation from the mean.
In the given que:
X 1 2 3 4
P(X) .5 .3 .1 .1
For mean :
Mean = 1(.5) + 2(.3) + 3(.1) + 4(.1)
= 1.8
For standard deviation :
Standard deviation = √.5(1-1.8)² + .3(2-1.8)² + .1(3-1.8)² + .1(4-1.8)²
= .98

Answer:
the 25 stickers put in the book
Step-by-step explanation:
The computation of the number of stickers put in the book is shown below:
Given that
There is 200 pages in a sticker book
And, each sticker takes 1 by 8 page
So, the number of stickers put in the book is
= 200 × 1 ÷ 8
= 25 stickers
hence, the 25 stickers put in the book
