A ) The angle formed by 2 consecutive radii:
Ф= 360° : 8 = 45°
b ) The angle formed by a radius and a side of a polygon:
α = (180° - 45°): 2 = 135° : 2 = 67.5°
Answer:
B ) 45°, 67.5°
Answer:
4
units
Step-by-step explanation:
The given shape is a right triangle and in right triangles the sum of square length of legs is equal to square length of hypotenuse (represented with x in here):
12^2 + 32^2 = x^2
1168 = x^2 find the root for both sides
4 =x
In the 500 spin test, 4 was chosen 121 times. This mean it was chosen 121 times out of 500, or 121/500.
Now, we need to convert this into a percent. We do this by dividing the numerator by the denominator, and multiplying the result by 100.
121/500 * 100 = 24.2, so the probability of spinning a 4 is 24.2%.
Answer:
x=22
Step-by-step explanation:
To find the x value, you need to use reverse PEMDAS (or GEMDAS as I've seen some people call it)
First, you subtract 4 from both sides of the equation. This should give you:
1/2x=11
Then, you divide 1/2 on each side. Although it's easier to multiply 2 on each side instead. This will give you.
x=22
