Answer:
x = 73.17
Step-by-step explanation:
To solve this problem we are going to have to use trig function
The three main trig functions are
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Hypotenuse
( where hypotenuse = longest length , opposite = side length opposite of angle and adjacent = other side length )
Here, we are given two side lengths and we want to find an angle.
We are given the hypotenuse and its adjacent ( we know this because we are not given its opposite )
When you have the adjacent and hypotenuse you use cosine.
So we have Cos"x" = adj / hyp
adj = 22 and hyp = 76
So Cos"x" = 22/76
==> take the inverse of cos to both sides
x = 73.17 ( rounded to the nearest hundredth )
and we are done!

Answer:
length is 7 inches and the width is 5 inches
Step-by-step explanation:
Hello, I think I can help you with this
the area of a rectangle is given by:
Step 1
According to the question data,the length is two inches longer than its width.which means that you can take the width and add 2 inches to obtain the length, in mathematical terms
(equation 2)Width + 2 inches = length
Step 2
Now, put equation 2 into equation 1
Step 3
replace and solve for w
Let
A=35
so, the width is 5 inches,
replacing this value in equation 2
Width + 2 inches = length
5 in +2 in =length
7 in = length
so , the length is 7 inches
Have a good day.

Answer:
c) 1.8 miles
Step-by-step explanation:
Assuming Kayla walks at a constant speed, we have ...
miles/minutes = 3.2/45 = x/25
x = 25(3.2/45) = 1.777... ≈ 1.8 . . . . miles
Kayla walks about 1.8 miles in 25 minutes.
The three geometric means between 3 and 512 are…
8, 32, 128
OR
-8, 32, -128
