Sides: a = 122 b = 122 c = 122
Area: T = 6444.961
Perimeter: p = 366
Semiperimeter: s = 183
Angle ∠ A = α = 60° = 1.047 rad
Angle ∠ B = β = 60° = 1.047 rad
Angle ∠ C = γ = 60° = 1.047 rad
Height: ha = 105.655
Height: hb = 105.655
Height: hc = 105.655
Median: ma = 105.655
Median: mb = 105.655
Median: mc = 105.655
Inradius: r = 35.218
Circumradius: R = 70.437
Vertex coordinates: A[122; 0] B[0; 0] C[61; 105.655]
Centroid: CG[61; 35.218]
Coordinates of the circumscribed circle: U[61; 35.218]
Coordinates of the inscribed circle: I[61; 35.218]
Exterior (or external, outer) angles of the triangle:
∠ A' = α' = 120° = 1.047 rad
∠ B' = β' = 120° = 1.047 rad
∠ C' = γ' = 120° = 1.047 rad
Step-by-step explanation:
It's A. 8x8 is 64. Therefore, 8cm is correct.
Answer:
7.41 m/s
Step-by-step explanation:
Force of a car inclined at an angle
F=mg Sin Θ where; m = 2956 kg , g = 9.8m/s² , Θ = 35⁰
F = 2956 x 9.8 x Sin 35 = 16615.82 N
Net force due to friction = 16615.82 - 3080 = 13535.82 N
To calculate acceleration; F= Ma
13535.82 = 2956 x a
a = 4.58 m/s²
From equation of motion
V² = 0 + (2 x 4.58 x 6)
V = 
V = 7.41 m/s
Answer:
Step-by-step explanation:
So, first lets the probability of just finding a yellow marble. There are 9+5+2+4 marbles in total, and that is 19 marbles.
5 out of those 20 are yellow, so the probabilty is 5/20 which is 1/4 or 20%
Then, lets do just finding the probability of a color that isn't blue.
Out of 20 marbles, 11 are color not blue, and 9 are.
So that probability is 11/20
Now, I think we need to do 11/20-5/20 so 6/20=3/10
Im so sorry, I might be wrong. I found both probabilities but I dont know if my final step is right.
56÷2=28
28-1=27
so the smaller number is 27
