Answer:

B is 20 c is 320

Step-by-step explanation:

B is 20 degrees, c is 160 degrees.

A straight line is 180 degrees, but because there are 2 lines, they cut into each-other causing there to be 4 angles, 2 pairs of the same amount, let the known angle be angle A.

Angle A and angle B are the same, Angle A is 20 degrees meaning that angle B is 20 degrees, leaving 160 degrees to be what c equals

Angle B= 20 degrees

Angle C= 160 degrees

Answer:

30240

Step-by-step explanation:

There are 10 possibilities for the first time slot.

After that, there are 9 possibilities for the second time slot.

So on and so forth.

The number of ways five time slots can be assigned is:

10×9×8×7×6 = 30240

Or, using permutation notation, ₁₀P₅.

Which, if any, of A. (4, π/6), B. (−4, 7π/6), C. (4, 13π/6), are polar coordinates for the point given in Cartesian coordinates
alisha [4.7K]

Answer:

The polar coordinates of }\left(2,\:2\sqrt{3}\right) are \left(4,\:\frac{\pi }{3}\right).

Step-by-step explanation:

To convert Cartesian coordinates \:\left(x,\:y\right) to Polar coordinates \:\left(r,\:\theta \right) apply:

r=\sqrt{x^2+y^2}\quad \theta =\arctan \left(\frac{y}{x}\right)

x=2\\\\y=2\sqrt{3}

r=\sqrt{x^2+y^2}\\r=\sqrt{2^2+\left(2\sqrt{3}\right)^2}\\r=4

\theta =\arctan \left(\frac{y}{x}\right)\\\theta=\arctan \left(\frac{2\sqrt{3}}{2}\right)\\\theta=\frac{\pi }{3}

The polar coordinates of }\left(2,\:2\sqrt{3}\right) are \left(4,\:\frac{\pi }{3}\right).
