Answer:
y = 163
Step-by-step explanation:
Because of the theorem that states the vertically opposite angles are equal, we can look at the opposite angle in this problem to find the answer. In this case, we can see that the opposite angle is 163, so y = 163.
2 angles opposite from each other are vertical angles.
Vertical angles are equal to each other.
Since Y is opposite the given angle of 163 degrees, Y = 163.
B. 4
cos(45°) = x/4√2
√2/2 = x/4√2
x = 4√2•√2/2
x = 4
There you go
4/7/(5)=4/(7×5)=4/35
It is Rational.
