Step-by-step explanation:
just use pythagoraus theorem
Answer:
x ≈ 4.5
Step-by-step explanation:
First, use the Pythagorean theorem to find the missing variable with side 8 and hypotenuse 10.
a² + b² = c²
a² + 8² = 10²
Square the variables
a² + 64 = 100
Subtract 64 from both sides.
a² = 36
Take the square root of both sides.
a = 6.
Now we can find the other triangle and we now know that one side is 4 and the hypotenuse is 6.
a² + b² = c²
x² + 4² = 6²
Square the variables.
x² + 16 = 36
Subtract 16 from both sides.
x² = 20
Square root. (refresh if you don't see this part.)
[tex]x=\sqrt{20}\\\text{Factor out a 2.}\\x=2\sqrt{5}[/tex]
Converted to decimal to the nearest tenth, the answer is
x = 4.5.
Now let's prove it.
[tex]a^2+b^2=c^2\\\text{Substitute variables.}\\(2\sqrt{5})^2+4^2=6^2\\\text{Factor the 2 in.}\\(\sqrt{20})^2+4^2=6^2\\\text{Square the variables.}\\20+16=36\\\text{Add.}\\36=36[/tex]

A horse runs in a field the speed time graph represents the first 12 seconds of the run after how many seconds had the horse run a distance of 75 metres
Answers
Answer:
9.5 seconds
Step-by-step explanation:
0-4 seconds => 20 meters
4-9.5 seconds => 55 meters
total = 75 meters
A horse run a distance of 75 metres in 9.5 seconds.
What is Speed?
The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance traveled by a body in a given period of time.
Here, From the graph,
when, t = 4 sec.
distance = 4 X 10 X 1/2
= 20 meters
Now, 75 - 20 = 55 meters
So, 55/10 = 5.5 seconds
Total time = 5.5 + 4
= 9.5 sec.
A horse run a distance of 75 metres in 9.5 seconds.
Thus, A horse run a distance of 75 metres in 9.5 seconds.

Two numbers have a sum of 18, and 4 times the first number minus the second number is equal to 17. What is the smallest number?
Answers
Answer:
The smallest number is 7
Step-by-step explanation:
Using simultaneous equation;
x+y = 18.....(1)
4x-y = 17.....(2)
from equation (1)..
x+y = 18
y = 18-x...(3)
substitute y into equation (2)
4x-y = 17
4x-(18-x) = 17
4x-18+x = 17
4x+x = 17+18
5x = 35
x = 35÷5
x = 7
substitute x into equation (3)
y = 18-x
y = 18-7
y = 11
Therefore; x=7
y=11
11+7=18
(4×7)-11=17
the smallest number is 7

Answers
Answer: There are two solutions and they are
theta = 135
theta = 225
=============================================================
Explanation:
Recall that x = cos(theta). Since the given cosine value is negative, this indicates x < 0. Theta is somewhere to the left of the y axis, placing it in quadrant 2 or quadrant 3.
It turns out there are two solutions, with one solution per quadrant mentioned above. Use the unit circle to find that the two solutions are:
theta = 135
theta = 225
You're looking for points on the unit circle that have x coordinate equal to x = -sqrt(2)/2. Those two points correspond to the angles of 135 and 225, which are in quadrants 2 and 3 respectively.
--------
I recommend using your calculator to note that
-sqrt(2)/2 = -0.70710678
cos(135) = -0.70710678
cos(225) = -0.70710678
The decimal values are approximate. Make sure your calculator is in degree mode. Because those three results are the same decimal approximation, this indicates that cos(135) = cos(225) = -sqrt(2)/2.

Step-by-step explanation:
you will always have 21 free CDs so you can put a closed circle on 21 then you can have a max of 15 CDs (180/12) soo put another closed circle on 36
now time for tapes, which is easier, the minimum is 0 and the max is 22.5. Now put closed circles on each and you're done. Except that .5 might get you in trouble, use your own discretion on rather to leave it on the .5 or round. I don't know what your teacher is looking for so I will let you decide.
