Solve the triangle.
Reika [66]

Answer:

cute scalene triangle.

Sides: a = 1   b = 2   c = 1.906

Area: T = 0.94

Perimeter: p = 4.906

Semiperimeter: s = 2.453

Angle ∠ A = α = 29.543° = 29°32'36″ = 0.516 rad

Angle ∠ B = β = 80.457° = 80°27'24″ = 1.404 rad

Angle ∠ C = γ = 70° = 1.222 rad

Height: ha = 1.879

Height: hb = 0.94

Height: hc = 0.986

Median: ma = 1.888

Median: mb = 1.147

Median: mc = 1.262

Inradius: r = 0.383

Circumradius: R = 1.014

Vertex coordinates: A[1.906; 0] B[0; 0] C[0.166; 0.986]

Centroid: CG[0.691; 0.329]

Coordinates of the circumscribed circle: U[0.953; 0.347]

Coordinates of the inscribed circle: I[0.453; 0.383]

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

∠ A' = α' = 150.457° = 150°27'24″ = 0.516 rad

∠ B' = β' = 99.543° = 99°32'36″ = 1.404 rad

∠ C' = γ' = 110° = 1.222 rad

Malcom coasted 32 miles from moon ridge to me tone and then pedaled back hard. If the round trip took 4 hours, what was malcoms
AURORKA [14]

Answer:

Malcom's average speed was 16 miles/hour.

Step-by-step explanation:

Given:

Distance from moon ridge to me tone = 32 miles.

Now including returned back journey.

So we can say that.

Total distance traveled = 32+32 =64\ miles

Also Given:

Time taken to travel total distance = 4 hours.

We need to find the average speed in miles per hour.

Solution:

Now we know that;

average speed is equal to Total distance traveled divided by Total time taken to travel the total distance.

framing in equation form we get;

average speed = \frac{64}{4}=16 \ mi/hr

Hence Malcom's average speed was 16 miles/hour.
