Answer:
Equilateral Triangle
Side a = 1
Side b = 1
Side c = 1
Angle ∠A = 60° = 1.0472 rad = π/3
Angle ∠B = 60° = 1.0472 rad = π/3
Angle ∠C = 60° = 1.0472 rad = π/3
C=60°B=60°A=60°b=1a=1c=1
Area = 0.43301
Perimeter p = 3
Semiperimeter s = 1.5
Height ha = 0.86603
Height hb = 0.86603
Height hc = 0.86603
Median ma = 0.86603
Median mb = 0.86603
Median mc = 0.86603
Inradius r = 0.28868
Circumradius R = 0.57735
Vertex coordinates: A[0, 0] B[1, 0] C[0.5, 0.86603]
Centroid: [0.5, 0.28868]
Inscribed Circle Center: [0.5, 0.28868]
Circumscribed Circle Center: [0.5, 0.28868]
Step-by-step explanation:
So it would be 3s + 7s + 11s + 15s + 19s + 23s + 27s. Hope this helps
Radians = degrees * pi/180 therefore
120 degrees * pi /180 = 2/3 pi
Multiply 3&8 and 3&7, this expands it to 24 + 21.
Answer:
2!
Step-by-step explanation:
2nd one since it's the only the negative one after multiplying, others will become positive, since there are two negatives which cancels!
Hope this helps!
