P=a+b+c
Right scalene triangle.
Sides: a = 21 b = 8 c = 22.472
Area: T = 84
Perimeter: p = 51.472
Semiperimeter: s = 25.736
Angle ∠ A = α = 69.146° = 69°8'44″ = 1.207 rad
Angle ∠ B = β = 20.854° = 20°51'16″ = 0.364 rad
Angle ∠ C = γ = 90° = 1.571 rad
Height: ha = 8
Height: hb = 21
Height: hc = 7.476
Median: ma = 13.2
Median: mb = 21.378
Median: mc = 11.236
Inradius: r = 3.264
Circumradius: R = 11.236
Vertex coordinates: A[22.472; 0] B[0; 0] C[19.624; 7.476]
Centroid: CG[14.032; 2.492]
Coordinates of the circumscribed circle: U[11.236; -0]
Coordinates of the inscribed circle: I[17.736; 3.264]
Exterior (or external, outer) angles of the triangle:
∠ A' = α' = 110.854° = 110°51'16″ = 1.207 rad
∠ B' = β' = 159.146° = 159°8'44″ = 0.364 rad
∠ C' = γ' = 90° = 1.571 rad
Answer:
254
Step-by-step explanation:
Divide 9 by 120, to get 0.075
Divide 19.05 by 0.075
Answer:
12 in.
Step-by-step explanation:
The perimeter is calculated by adding all up the sides of a shape. In this case, the shape is a square, considering that all the sides are the same measurements. 3+3+3+3 can be simplified to 3x4. This gives you 12 in. as the perimeter.
Answer:
lets find the exact value of w
7w - 7 = 7
+7 +7
7w = 14
/7 /7
w = 2
Now let's replace w with 2
5(2) + 1 = 11
