Answer:
1/5
Step-by-step explanation: You add 4+10+6 to get 20. So the probability that the spinner lands on red would be 4/20. If you need it simplified you take 4 and divide it by 4 to get 1, then you would divide 20 by 4 to get 5. that would leave you with 1/5.

What is Trigonometry?One of the six mathematical functions used to express the side ratios of right triangles, the trigonometric function includes the sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). The figure shows these six trigonometric functions in respect to a right triangle. Surveying, engineering, and navigation issues where one of a right triangle's acute angles and the length of a side are known but the lengths of the other sides need to be determined can be solved with ease using trigonometry.
As per the given data:
x = 41 cm
v = 17 cm
∠W = 134°
To find the length of w:
From the cosine law: [tex]cos(W) = \frac{x^2 + v^2 - w^2}{2xv}[/tex]
[tex]w = \sqrt{x^2 + v^2 - 2xvcos(W)}\\w = \sqrt{(41)^2 + (17)^2 - 2(41)(17)cos(W)}\\w = \sqrt{1681 + 289 + 968.35} = \sqrt{2938.35}\\w = 54 \:cm[/tex]
Hence, the length of w is 54 cm.

Quadrilateral ABCD is inscribed in the circle. What is the measure of angle C?
Answer: 92
Step-by-step explanation: Angles in an inscribed quad are supplementary and add to 360.
First solve for x:
2x+34=180
x = 73
Then, solve for c
3x + 49 + c = 360
3(73) + 49 + c = 360
268 + c = 360
c = 92

How likely is it that the spinner will land on a green space?
Answer:
1/5
Step-by-step explanation:
Answer:
1/5
Step-by-step explanation:
Solve the following quadratic equation
(x-18)^2=1.
A. x = 19 and x = 17
B. x = -19 and x = -17
C. x = -19 and x = 17
D. x = 19 and x = -17
To solve the quadratic equation (x - 18)^2 = 1, we can take the square root of both sides and consider the positive and negative roots. Here's how we can proceed:
Taking the square root of both sides gives us:
x - 18 = ±√1
Simplifying the square root of 1, we have:
x - 18 = ±1
Now, let's solve for x by considering both the positive and negative cases:
Case 1: x - 18 = 1
Adding 18 to both sides:
x = 1 + 18
x = 19
Case 2: x - 18 = -1
Adding 18 to both sides:
x = -1 + 18
x = 17
Leading to our final correct answer is:
A. x = 19 and x = 17
