Ksenya-84 [330]3 years ago
3 0

Answer:

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

Answer:

46.2^o

Step-by-step explanation:

<u><em>The correct question is</em></u>

If b = 9 and c = 13, what is the measure of ∠A? (round to the nearest tenth of a degree)

The picture in the attached figure

we know that

In the right triangle ABC

cos(A)=\frac{b}{c} ---> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

cos(A)=\frac{9}{13}

using a calculator

A=cos^{-1}(\frac{9}{13})=46.2^o

The segments shown below could form a triangle?
Leni [432]

Answer:

<em>Option B; False</em>

Step-by-step explanation:

Consider a Triangle Inequality to prove that these segments could form a triangle;

| a - b | < c < a + b,\\| c - a | < b < a + c,\\| c - b | < a < b + c, Considering - a - segment AC ( 8 units ) - b - BC ( 7 units ), -  c - BC ( 15 units )\\\\| 8 - 7 | < 15 < 8 + 7,\\1 < 15 < 15, Now 15 is not < 15, it is =, thus ;\\Solution ; False

<em>These segments could not form a triangle</em>
