Step-by-step explanation:
Answer : 12.9 units
explanation :
Sides: a = 7.616 b = 7.211 c = 13.038
Area: T = 23
Perimeter: p = 27.865
Semiperimeter: s = 13.933
Angle ∠ A = α = 29.291° = 29°17'29″ = 0.511 rad
Angle ∠ B = β = 27.597° = 27°35'50″ = 0.482 rad
Angle ∠ C = γ = 123.111° = 123°6'41″ = 2.149 rad
Height: ha = 6.04
Height: hb = 6.379
Height: hc = 3.528
Median: ma = 9.823
Median: mb = 10.05
Median: mc = 3.536
Inradius: r = 1.651
Circumradius: R = 7.783
Vertex coordinates: A[3; -1] B[16; -2] C[9; -5]
Centroid: CG[9.333; -2.667]
Coordinates of the circumscribed circle: U[0; 0]
Coordinates of the inscribed circle: I[3.158; 1.651]
Exterior (or external, outer) angles of the triangle:
∠ A' = α' = 150.709° = 150°42'31″ = 0.511 rad
∠ B' = β' = 152.403° = 152°24'10″ = 0.482 rad
∠ C' = γ' = 56.889° = 56°53'19″ = 2.149 rad
Answer:
Lower and Upper Class Limit
Step-by-step explanation:
The Lower class limit is the smallest value within the class and the Upper class limit is the largest value within the class.
In a grouped data, data are distributed into classes with a specific class size/interval. e.g. The Class 0-4 has a Class Size of 5. The Lower class limit in this case is 0 and the Upper Class Limit is 4.
Answer:
20x=2
Divide by 20
X=2/20
X=0.1
Step-by-step explanation:
if we take 31 to be the 100%, what is 28 off of it in percentage?
![\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 31&100\\ 28&x \end{array}\implies \cfrac{31}{28}=\cfrac{100}{x}\implies 31x=2800\implies x=\cfrac{2800}{31} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill x\approx 90.32~\hfill](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Bccll%7D%20amount%26%5C%25%5C%5C%20%5Ccline%7B1-2%7D%2031%26100%5C%5C%2028%26x%20%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B31%7D%7B28%7D%3D%5Ccfrac%7B100%7D%7Bx%7D%5Cimplies%2031x%3D2800%5Cimplies%20x%3D%5Ccfrac%7B2800%7D%7B31%7D%20%5C%5C%5C%5C%5B-0.35em%5D%20%5Crule%7B34em%7D%7B0.25pt%7D%5C%5C%5C%5C%20~%5Chfill%20x%5Capprox%2090.32~%5Chfill)
