Find the value of 2 in the triangle shown below.
O
2 =
3.5
4
55°
3.5

Sides: a = 2   b = 2  c = 2

Step-by-step explanation:

Equilateral triangle.

Sides: a = 2   b = 2   c = 2

Area: T = 1.732

Perimeter: p = 6

Semiperimeter: s = 3

Angle ∠ A = α = 60° = 1.047 rad

Angle ∠ B = β = 60° = 1.047 rad

Angle ∠ C = γ = 60° = 1.047 rad

Height: ha = 1.732

Height: hb = 1.732

Height: hc = 1.732

Median: ma = 1.732

Median: mb = 1.732

Median: mc = 1.732

Inradius: r = 0.577

Circumradius: R = 1.155

Vertex coordinates: A[2; 0] B[0; 0] C[1; 1.732]

Centroid: CG[1; 0.577]

Coordinates of the circumscribed circle: U[1; 0.577]

Coordinates of the inscribed circle: I[1; 0.577]

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:

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
