Answer:
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 <em>degrees mode</em>.
Answer:
This may help but I think you mean cosine function it means
The cosine function is one of the basic functions encountered in trigonometry (the others being the cosecant, cotangent, secant, sine, and tangent). Let be an angle measured counterclockwise from the x -axis along the arc of the unit circle. Then is the horizontal coordinate of the arc endpoint.

Answer:
-274
Step-by-step explanation:
425 - 699...is the same as 699 - 425...but after using this type of a method...remember to put a negative on your answer
:699 - 425 = 274
but the equation is 425 - 699...so your answer would be ( -274)
Answer:
1/2³
Step-by-step explanation:
