You are correct it's 36 9/16
Answer:
n= 69 degrees
Step-by-step explanation:
total inside measure of any triangle is 180 degrees
180= n+n+42
180= 2n+ 42
2n= 180-42
2n= 138
n=69
Assuming the plus sign is supposed to be an equal sign, the answer is 3/2. If not, the answer is 21/10.
Answer:
There are seven seventh roots of unity, e2πki7 , all on the unit circle, r=1 above.
The first one is at θ=2π7=360∘7=5137 ∘ , and there are others at 4π7,6π7,8π7,10π7,12π7 and of course at 0 radians, i.e. unity itself.
How to find?
There are 4 fourth roots of unity and they are 1, i,−1 and−i
Each of the roots of unity can be found by changing the value of k k k in the expression e 2 k π i / n e^{2k\pi i/n} e2kπi/n. By Euler's formula, e 2 π i = cos ( 2 π ) + i sin ( 2 π ) = 1.
