One side of the triangle is 8 in, and the other two sides are equal to a positive whole number of inches. What is the smallest p
frutty [35]
In a triangle the sum of two sides is always greater than the third side.

If one side = 8 in and other two sides are equal to a positive whole number, then the smallest possible sum of the other two sides = 9 in ⇒
<span>Smallest possible perimeter = 8 + 9 = 17 in</span>

Find the coordinates of the point (x,y) at the given angle θ on a circle of radius r centered at the origin. Show all work. Roun
beks73 [17]

Answer:

(i) The equivalent coordinates in rectangular form are (x, y) = (-3.277,-2.294).

(ii) The equivalent coordinates in rectangular form are (x, y) = (0.866, 0.5).

Step-by-step explanation:

In this exercise we must find the equivalent coordinates in rectangular form from polar form. That is:

(x, y) = (r\cdot \cos \theta, r\cdot \sin \theta)

Where:

r - Norm of vector, dimensionless.

\theta - Direction of vector with respect to +x semiaxis, measured in sexagesimal degrees.

(i) (r = 4, \theta = 215^{\circ})

(x. y) = (4\cdot \cos 215^{\circ}, 4\cdot \sin 215^{\circ})

(x, y) = (-3.277,-2.294)

The equivalent coordinates in rectangular form are (x, y) = (-3.277,-2.294).

(ii) (r = 1, \theta = 30^{\circ})

(x. y) = (1\cdot \cos 30^{\circ}, 1\cdot \sin 30^{\circ})

(x, y) = (0.866, 0.5)

The equivalent coordinates in rectangular form are (x, y) = (0.866, 0.5).
