Answer:
see below
Step-by-step explanation:
cos ( x+pi/2) = -sinx
We know that
cos(A + B) = cos A cos B - sin A sin B
Let x = A and pi/2 = B
cos x cos pi/2 - sin x sin pi/2 = -sin x
We know cos pi/2 = 0 and sin pi/2 = 1
cos x * 0 - sin x *1 = -sin x
- sin x = - sin x
Answer:
Clustering
Step-by-step explanation:
Data groups that are grouped closely together
Rule to convert from DMS (degrees minutes seconds) format to pure degrees:
x deg, y min, z sec = x+y/60+z/3600
Use that rule to get...
88 deg, 22 min, 45 sec = (88+22/60+45/3600) degrees
88 deg , 22 min, 45 sec = 88.3791667 degrees (approx)
Now use the tangent function on your calculator
tan(88.3791667) = 35.34015179
Answer is choice C. It's not a perfect match due to some rounding errors, but it's close enough.
