Answer:
area =4*13*12=624
Therefore the area is 626 units square
Triangle a - acute
Triangle b - acute
Triangle c - acute
Triangle d - right
Answer:
60.2 m
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you ...
Tan = Opposite/Adjacent
The width of the river is the side of a right triangle opposite the angle of 76°. The 15 m distance is the length of the side adjacent to the measured angle. So, we have ...
tan(76°) = width/(15 m)
Multiplying by 15 m, we get ...
width = (15 m)tan(76°) ≈ 60.2 m
The width of the river is about 60.2 m.
Step-by-step explanation:
Side a = 63
Side b = 21
Side c = 66.40783 = 21√10
Angle ∠A = 71.565° = 71°33'54" = 1.24905 rad
Angle ∠B = 18.435° = 18°26'6" = 0.32175 rad
Angle ∠C = 90° = 1.5708 rad = π/2Area = 661.5
Perimeter p = 150.40783
Semiperimeter s = 75.20392
Height ha = 21
Height hb = 63
Height hc = 19.92235
Median ma = 37.85829
Median mb = 63.86901
Median mc = 33.20392
Inradius r = 8.79608
Circumradius R = 33.20392
Vertex coordinates: A[0, 0] B[66.40783, 0] C[6.64078, 19.92235]
Centroid: [24.34954, 6.64078]
Inscribed Circle Center: [12.20392, 8.79608]
Circumscribed Circle Center: [33.20392, 0]
The coordinates represent the numbers of plants of each type she can use and minimize the cost
Let x be the number of plants of one type.
y be the number of plants of the other type.
<h3>What is the meaning of the
vertex of the
feasible region?</h3>
The optimal solutions will occur at one or more of the extreme points this is the vertices of the feasible region.
We have, The vertex of the feasible region that results in the minimum value of the cost function is (5,39).
That means buying 5 of one type of plant and 39 of the other type of plant results in the lowest cost.
Thus the coordinates represent the numbers of plants of each type she can use and minimize the cost.
