Tan13pi/4 a. use the fact that there are 2pi radians in each circle to find another angle, smaller than 2 pi, that is equivalent to 13pi/4. b. find the tangent of the angle you found in part a. this is also 13pi/4.

Step-by-step explanation:

Tan 13π/4 = tan(3π + 1/4π)

According to the trigonometry identity;

tan(A+B) = tanA + tanB/1-tanAtanB

If A = 3π and B = π/4

tan(3π + 1/4π) = tan 3π + tanπ/4/1-tan3πtanπ/4

If πrad = 180°

tan(3π + 1/4π) = tan 540° + tan45°/1-tan540°tan45°

tan(3π + 1/4π) = 0+1/1-0(1)

tan(3π + 1/4π) = 1/1-0

tan(3π + 1/4π) = 1/1

tan(3π + 1/4π) = 1

tan 13π/4 = 1

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
