What is the measure of angle n to the nearest whole degree?

9°

Step-by-step explanation:

You can make use of any of the trigonometric ratios to determine N, or you can let your calculator tell you what it is by solving the triangle.

SOH CAH TOA reminds you that

... sin(N) = 13/85 . . . . N = arcsin(13/85)

... cos(N) = 84/85 . . . N = arccos(84/85)

... tan(N) = 13/84 . . . . N = arctan(13/84)

all will tell you N ≈ 8.79741° ≈ 9°

_____

If you use inverse functions on your calculator, be sure it is in degrees mode.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
