Answer:
While determining the angle
with the tangent ratio or cotangent ratio uses the same sides lengths but the ratios are inverse of each other.
Step-by-step explanation:
See the diagram attached.
Let us assume a right triangle Δ ABC with ∠ B = 90°. Now, assume that the angle ∠ CAB =
and the sides AB, BC, CA are 3, 4, 5 units respectively.
The tangent ratio of an angle
is given by
Again, the cotangent ratio of angle
is given by
Therefore, in both the cases of tangent ratio and cotangent ratio are inverse of each other and while determining the angle
with the tangent ratio or cotangent ratio uses the same sides lengths but the ratios are inverse of each other. (Answer)
Answer:
The second part of 72 is 
Step-by-step explanation:
The whole part is given as = 72
One part of it = 1/3
Let the other part of it = k
Now,according to the question:
First Part + Second Part = 72
or, 
⇒
or, 
or, k = 215/3
Hence, the second part of 72 is

Answer: 3(3w - 51)
Answer:
D
Step-by-step explanation:
You have the opposite side given and the adjacent side. That means you will use the tangent.
Tan(theta) = opposite / adjacent
opposite = 6
adjacent = 3.5
Tan(theta) = 6 / 3.5
Tan(theta) = 1.714
Tan-1(1.714) = 59.74
when you get an answer over 1 from the division, you know that the angle is over 45 degrees.
