Answer:

Its 67.9 but technically its 67.912 *hope this helps

Step-by-step explanation:

Right scalene triangle.

Sides: a = 66 b = 16 c = 67.912

Area: T = 528

Perimeter: p = 149.912

Semiperimeter: s = 74.956

Angle ∠ A = α = 76.373° = 76°22'23″ = 1.333 rad

Angle ∠ B = β = 13.627° = 13°37'37″ = 0.238 rad

Angle ∠ C = γ = 90° = 1.571 rad

Height: ha = 16

Height: hb = 66

Height: hc = 15.55

Median: ma = 36.674

Median: mb = 66.483

Median: mc = 33.956

Inradius: r = 7.044

Circumradius: R = 33.956

Vertex coordinates: A[67.912; 0] B[0; 0] C[64.142; 15.55]

Centroid: CG[44.018; 5.183]

Coordinates of the circumscribed circle: U[33.956; 0]

Coordinates of the inscribed circle: I[58.956; 7.044]

Exterior (or external, outer) angles of the triangle:

∠ A' = α' = 103.627° = 103°37'37″ = 1.333 rad

∠ B' = β' = 166.373° = 166°22'23″ = 0.238 rad

∠ C' = γ' = 90° = 1.571 rad

Find the 8th term 50,20,8

Answers

Answer:

Step-by-step explanation:

Answer:

0.08192

Step-by-step explanation:

Given 50, 20, 8, ...

The sequence is geometric in nature

The nth term of the geometric sequence is exoressed as;

Tn = ar^{n-1}

a is the first term = 50

r is the common ratio = 20/50 = 8/20 = 2/5

n is the number of term = 8 (since we need the 8th term)

Substitute

T8 = 50(2/5)^{8-1}

T8 = 50(2/5)^7

T8 = 50(128/78,125)

T8 = 0.08192

Hence the 8th term is 0.08192.

Zeros can be observed graphically or solved for algebraically. A linear function can have none, one, or infinitely many zeros. If the function is a horizontal line ( slope = [latex]0[/latex]), it will have no zeros unless its equation is [latex]y=0[/latex], in which case it will have infinitely many.

Answers

Answer:

Step-by-step explanation:

5 square inches is the area of triangle PQR in square inches.

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

Given a triangle PQR.

We need to find the measurement is closest to the area of triangle PQR in square inches.

The PR is 2.6 inches in height and RQ is 4.1 inches.

We know that area of triangle is 1/2 times base and height.

By using ruler we calculated the height of triangle is 2.6 inches and base is 4.1 inches

The formula for area is

Area=1/2(Base×Height)

Plug in the values of base and height

=1/2(4.1×2.6)

=1/2(10.66)

=5.33

=5 square inches

Hence, 5 square inches is the area of triangle PQR in square inches.
