For which of the quadrant angles 0, pi/2, pi, and 3pi/2 is the cos function equal to 0? (Select all that apply.) 0, pi/2, pi, 3pi/2

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

true

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.

im not sure of the names, but the answer is 48
