Answer:
38.22
Step-by-step explanation:
Arc length = fraction of the circle * circumference
10 = fraction of the circle * 2*pi *15
10 = fraction of the circle * 30pi
Divide by 30 pi
10/30pi = fraction of the circle
1/3pi = fraction of the circle
A circle is 360 degrees
1/ (3*3.14) = x/360
1/9.42 = x/360
Multiply each side by 360
360/9.42 = x
38.21656051
Rounding to the nearest hundredth
38.22 degrees
Answer:
"proportional to"
Step-by-step explanation:
The sign ∝ means 'is proportional to'. This is used to show that one variable of value is proportional to another value or variable.
Example:
- x ∝ y ('x' is proportional to 'y')
Hope this helps.
A because it’s the only one that makes the best sense
B does not make sense it is the opposite of what ur trying to find
C is not a correct percentage, the correct Percentage would be 53.84%
D which can’t be correct because choice b and c are not correct
The height of glass 1 which in cylindrical in shape is 7.6
centimeters. Since the total volume of water added by Celia is 100 cubic
centimeter, and the volume of glass 2 is 26.4 cubic centimeter which is a
conical in shape. Subtracting the volume of glass 2 from the total volume glass
1 can be calculated and its height.
Answer:
- x = 30°
- RS = 30°, SR = TU = 120°, UR = 90°
- ∠P = 45°
- ∠UTS = 60°
Step-by-step explanation:
(a) If RS = x, then the sum of arcs around the circle is ...
x + 4x +4x +3x = 360°
12x = 360°
x = 30°
__
(b) Based on the given ratios, the arc measures are computed from x. For example, ST = TU = 4x = 4(30°) = 120°
- RS = 30°
- ST = 120°
- TU = 120°
- UR = 90°
__
(c) Angle P is half the difference of arcs TU and RS:
∠P = (TU -RS)/2 = (120° -30°)/2
∠P = 45°
__
(d) Inscribed angle UTS is half the measure of the arc it intercepts. Arc RU has the measure (30° +90°) = 120°, so the measure of UTS is ...
∠UTS = 120°/2 = 60°
