Answer:
Step-by-step explanation:
First count the number of sides. There are 6 sides.
Now use the formula
(n - 2) * 180 To determine the total of all 6 angles.
(6 -2) * 180 =
4 * 180 = 720
Is that a 9 in x + 9 [lower left]? I'll assume so. Edited to show it was a 4.
x + 4 + 120 + x + 50 + 140 + 112 + x = 720 Combine
3x + 4 + 120 + 50 + 140 + 112 = 720
3x + 426 = 720 Subtract 431 from both sides
3x = 720 - 426 Combine
3x = 294 Divide by 3
x = 294/3
x = 98
Hey! Hope that I can help.
-√17 belongs in only one number set: irrational.
2 because if 1/2 of 8 is 4 and 1/4 of 8 is = to 1/2 of 4, then 1/4 of 8 must be 2.
Answer:
NOT 100% sure! If its not this I think its 
The correct answer is B) 9 m.
The measure of the sector of circle R is 32π/9 m. The measure of the central angle is 80°. This means that the sector is 80/360 = 2/9 of the circle. The area of a circle is given by A=πr², so the area of the sector is A=2/9πr². To verify this, 2/9π(4²) = 2/9π(16) = 32π/9.
Using this same formula for circle S, we will work backward to find the radius:
18π = 2/9πr²
Multiply both sides by 9:
18*9π = 2πr²
162π = 2πr²
Divide both sides by 2π:
162π/2π = 2πr²/2π
81 = r²
Take the square root of both sides:
√81 = √r²
9 = r
