My guess would probably be A = 21
<span>cotx = (cosx)/(sinx)
Where is this function not defined?
i.e. where is sin(x)=0?
Because at this point, cotx will be undefined because you cannot divide by zero. So find all points from 0 to 2 pi where sinx is 0.</span>
Answer:
d. x = 7
Step-by-step explanation:
32/8 = 28/x
simplify the fraction
4/1 = 28/x
cross multiply:
4x = 28
divide both sides by 4:
x = 7
