The value of the x is 3 and the measure of the arc is 154 degree if the angle APE is 90 degree.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)
We have a circle shown in the picture.
The angle APE = 90 degree (from the figure)
25x + 15 = 90
25x = 75
x = 3
The measure of arc CDE = (20x + 4) + (33x - 9) = 53x -5
= 53(3) -5
= 154 degree
Thus, the value of the x is 3 and the measure of the arc is 154 degree if the angle APE is 90 degree.

What expression has a value of 13?
Answer:
The answer is A) 5^2 + (2 x 1) - 14
Step-by-step explanation:
Use PEMDAS ( Parentheses, Exponent, Multiply or Divide, Add or Subtract)
5^2 + (2 x 1) - 14
5^2 + 2 - 14 Do what's in the parentheses
25 + 2 - 14 Then you will do the exponent
27 - 14 Then you subtract

given angle: 52º
missing angle 1: (15x + 3)º
missing angle 2: (3x - 1) º
Answer:
just know total angle sum is 180°
Step-by-step explanation:
[tex]52 + (15x + 3) + (3x - 1) = 180 \\ 52 + 3 - 1 + 15x + 3x = 180 \\ 54 + 18x = 180 \\ 18x = 180 - 54 \\ 18x = 126 \\ x = 7[/tex]
but give me a brainliest
Answer:
x = 7
Step-by-step explanation:
→ Find the sum of the angles
52 + 15x + 3 + 3x - 1 = 18x + 54
→ Wquate the expression to 180
18x + 54 = 180
→ Solve for x
x = 7

For which number is the experimental probability closest to the theoretical probability
Using it's concept, it is found that the experimental probability is closest to the theoretical probability for number 1.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
The theoretical probability is calculated before any experiments, while the experimental probability is calculated after experiments.
Considering that the sections are equal-sized, the expected frequency for each section is given by:
Ef = 450/8 = 56.25.
The closest frequency to 56.25 is of 58, associated with number 1, which is the one that has the closest probabilities.
